Introduction

The annual debate over renewal of normal trading status for the People's Republic of China (PRC) has raised an enormous debate in this country over the effectiveness of economic sanctions, a debate that comes on the heels of an explosive growth in the use of economic sanctions. During his first term, President Bill Clinton imposed new unilateral economic sanctions on 35 countries that make up 42 percent of the world's population and consume 19 percent of its exports. This trend raises important questions for U.S. policymakers: (1) Are economic sanctions an effective way to achieve U.S. foreign policy objectives? (2) What do economic sanctions cost the U.S. economy, and how do they harm American workers? (3) Do unilateral state and local economic sanctions undermine the coherence of U.S. foreign policy, reduce policy flexibility, and violate the U.S. Constitution? (4) What strategic doctrine should govern the use of economic sanctions to ensure that they actually advance U.S. interests?

A Poor Track Record

Historically, economic sanctions have a poor track record. Between 1914 and 1990, various countries imposed economic sanctions in 116 cases. They failed to achieve their stated objectives in 66 percent of those cases and were at best only partially successful in most of the rest.¹ Since 1973, the success ratio for economic sanctions has fallen precipitously to 24 percent for all cases.²

Although proponents often cite South Africa as an example of the successful application of economic sanctions, unique factors existed in that case that are unlikely to be found in other countries. Most important was the fact that the sanctions were imposed multilaterally by the international community, not solely by the United States. Even so, Pretoria succumbed to the pressure only after private business executives-fearing the Free South Africa Movement's disinvestment campaign would cause the price of company stocks to fall-went beyond government-mandated sanctions on new loans to and investments in South Africa, calling in current loans and liquidating existing investments in that country.

The Downside of Unilateral Economic Sanctions

Although multilateral sanctions might succeed under the appropriate circumstances, unilateral sanctions will fail more often than not. By itself, a unilateral trade or investment embargo may not be enough to persuade a country's government to change its objectionable policies. In today's global economy, foreign rivals quickly and easily replace American companies to meet the needs of a target country's market. In addition, unilateral economic sanctions applied against friendly countries because of single-issue disputes (for example, drug trafficking) may reduce cooperation on other more important issues and damage broader U.S. interests.

Unilateral economic sanctions cost the U.S. economy dearly. In 1995, economic sanctions reduced U.S. exports to 26 target countries by as much as $15 billion to $19 billion, eliminated more than 200,000 jobs in relatively high-wage export sectors, and caused American workers to lose nearly $1 billion in wages.³ Moreover, the effects-through lost follow-on sales and services, diminished foreign confidence in the reliability of American companies as suppliers, and reduced foreign direct investment in the United States-can reverberate through the U.S. economy long after sanctions have been removed.

Finally, economic sanctions imposed by individual states or localities are disruptive and tread on tenuous constitutional ground. They can interfere with the making of foreign policy by preventing the United States from speaking with one voice on international affairs. They also can undermine the President's ability to adapt U.S. foreign policy to changing circumstances. Moreover, unilateral state and local economic sanctions appear to violate both the Commerce Clause and the Supremacy Clause of the U.S. Constitution.

A New Strategic Doctrine on Economic Sanctions

Economic sanctions are important strategic weapons in the policy arsenal. Like other strategic weapons, however, they must be used with extreme care lest American companies and their workers, suppliers, and shareholders become friendly-fire casualties.

Because economic sanctions are only a step below a blockade or other military action, any decision to apply them should receive the same deliberate, sober consideration that is given to a decision that commits U.S. troops to battle. The widespread misapplication of unilateral economic sanctions by Congress and the President since the end of the Cold War suggests that such careful deliberation is not occurring. The United States needs a new strategic doctrine governing the use of economic sanctions to achieve U.S. foreign policy objectives. To fashion this new doctrine, Congress should:

1. Establish guidelines for implementing economic sanctions. Before Congress and the President consider imposing economic sanctions, the following remedies should have been exhausted in the order listed:

• Private persuasion.

• Public appeals.

• Consultation with allies on multilateral sanctions.

• Non-economic sanctions.

Economic sanctions to achieve clearly defined national security objectives should be treated differently from sanctions that are intended to serve a moral or economic purpose. In national security cases, they may be justified even if their probability of success is low.

For non-national security purposes, economic sanctions should be applied only if there is a high probability of success. To determine the likelihood that a proposed sanction aimed at other foreign policy objectives will be successful, Congress and the President should ask four questions:

• Is the proposed sanction's objective limited enough to be achievable?

• Does the United States have a monopoly advantage that it can exploit against the target and, if not, will other countries cooperate with the United States to impose the sanction?

• Is the sanction's likely impact so large that it may persuade the target to change its policies?

• Is the sanction's probable impact on the U.S. economy small enough not to cause significant harm to American companies and their workers, suppliers, and shareholders, as well as American consumers?

Congress and the President should proceed with a proposed economic sanction only if all of the above questions can be answered affirmatively. If they cannot, the sanction-even though it may please domestic constituency groups-has no realistic hope of achieving its objective and should be rejected.

2. Limit the application of the International Emergency Economic Powers Act (IEEPA) to clear-cut national security issues. Enacted in 1977, the IEEPA grants the President broad powers to regulate or prohibit trade, investment, and financial transactions with foreigners for purposes of dealing with a national security, foreign policy, or international economic emergency. These sweeping powers should be used only to counter real threats to national security interests. Congress should tighten the IEEPA to exclude so-called foreign policy and economy emergencies.

3. Mandate that the President consult with Congress within a set period following the imposition of economic sanctions by executive order. Just as the War Powers Resolution requires the President to receive congressional approval for any extended military engagement, Congress should approve, directly and expressly, any extended use of economic sanctions.

4. Direct the Secretary of Commerce to identify all American companies (including suppliers, shareholders, and employees) that have suffered material economic loss because of U.S. economic sanctions.

5. Direct the Council of Economic Advisers, in the Economic Report of the President, to publish an annual study of how much sanctions cost the U.S. economy.

6. Forbid state and local governments to impose economic sanctions when they interfere with national policy and security interests.

What are Economic Sanctions?

U.S. policymakers and officials utilize a variety of tools to influence the policies of other governments. These tools, in order of increasing severity, are diplomatic persuasion, public appeals, non-economic sanctions, economic sanctions, and military action. They may be applied either unilaterally or in conjunction with other countries through the United Nations (U.N.) or other international organizations.

Economic Sanctions
An economic sanction is any restriction imposed by one country (the sender) on international commerce with another country (the target) in order to persuade the target country's government to change a policy. Economic sanctions include:

• Limiting exports to the target country;

• Limiting imports from the target country;

• Restricting investment in the target country;

• Prohibiting private financial transactions between a sender country's citizens and the target country's citizens or government; and

• Restricting the ability of a sender country's government programs, such as the U.S. Export-Import Bank (Ex-Im Bank) and the Overseas Private Investment Corporation (OPIC), to assist trade and investment with the target country.

Non-Economic Sanctions
A sender country also may apply non-economic sanctions against a target country to persuade its government to change policy. In contrast to economic sanctions, which are intended to penalize a target country financially, non-economic sanctions are aimed at denying legitimacy or prestige. Although the following list is not exhaustive, non-economic sanctions include:

• Canceling ministerial and summit meetings with a target country;

• Denying a target country's government officials visas to enter the sender country;

• Withdrawing a sender country's ambassador or otherwise downgrading diplomatic and military contacts with a target country;

• Blocking a target country from joining international organizations;

• Opposing a target country's bid to host highly visible international events, such as the Olympics;

• Withholding foreign aid; and

• Instructing a sender country's directors to vote against new loans to a target country at the World Bank or other international financial institutions.

Policy Objectives of Economic Sanctions

Sender countries delineate three general categories of policy objectives for which economic sanctions may be applied: national security objectives, other foreign policy objectives, and international trade and investment dispute resolution.

National Security Objectives
Economic sanctions may be employed to deter military aggression or to force an aggressor to withdraw its armed forces from a disputed territory. In such circumstances, the U.N. Security Council may encourage countries to apply economic sanctions. For example, the United States participated in multilateral sanctions against Iraq following its invasion of Kuwait, and against parts of the former Yugoslavia following the outbreak of war there.

Economic sanctions may be used to curb weapons proliferation. The United States participates in a number of international regimes to control the export of militarily sensitive goods and technology, including the Wassenaar Arrangement,⁴ the Missile Technology Control Regime, and the Australia Group (chemical and biological weapons proliferation control).⁵ Sanctions against countries that seek to acquire weapons in violation of international regimes controlling the proliferation of nuclear, chemical, and biological weapons and missile technology are far more likely to be effective if applied multilaterally and targeted against the offending country's leaders and armed forces.

Economic sanctions may be used to punish a country that condones or sponsors terrorism. Terrorism-related sanctions usually have been applied unilaterally. For example, the United States prohibits investment in Iran and Libya, forbids trade with Libya, and severely restricts trade with Iran because Iran and Libya fund international terrorist organizations.⁶

The United States may wish to restrict the export of armaments and militarily sensitive technology to countries that, although not immediate threats, are considered potentially hostile to U.S. interests. Such restrictions, however, are more likely to be effective if applied multilaterally, in concert with military allies.

Other Foreign Policy Objectives
Economic sanctions may be employed to further other foreign policy objectives, such as the observance of human rights and democratization. For example, on May 20, 1997, President Clinton announced a ban on new investments in Myanmar (formerly Burma) because the ruling military junta had refused to recognize the victory of the opposition party in the May 1990 general election and had kept opposition leader and Nobel Peace Prize winner Aung San Suu Kyi under house arrest for six years.⁷

Three other reasons for employing economic sanctions are indicated by President Clinton's March 1, 1996, decision to cut off Ex-Im Bank and OPIC financing to Colombia because of Colombia's failure to control the traffic in illegal drugs;⁸ a July 1, 1996, decision by President Clinton suspending the duty-free designation for surgical instruments, leather gloves, certain sporting goods, and carpets imported from Pakistan under the Generalized System of Preferences (GSP) program because of Pakistan's failure to respect workers' rights;⁹ and a May 30, 1996, decision by directors of the Ex-Im Bank to deny financing to three U.S. exporters because of environmental concerns surrounding the construction of the Three Gorges Dam in China.¹⁰

International Trade and Investment Dispute Resolution Economic sanctions may be effective in the resolution of international trade and investment disputes. Most such disputes, however, are resolved satisfactorily through the dispute settlement procedures of the World Trade Organization, regional customs unions like the European Union, regional free trade agreements like the North American Free Trade Agreement, or other bilateral agreements. Even when economic sanctions are employed, a sender country's sanctions are usually limited and in proportion to a target country's alleged infraction. Because of their limited application, economic sanctions arising from international trade and investment disputes do not warrant further consideration in this analysis.

The Explosive Growth of Economic Sanctions

During the Cold War (1945-1989), most economic sanctions imposed by the United States were directed against communist countries and were intended to counter actual or potential military aggression; to deny advanced, militarily sensitive technology to the Soviet Union or its allies; and to control weapons proliferation. Economic sanctions with national security objectives usually were applied multilaterally in cooperation with other industrial democracies or (rarely) through the U.N.

Since 1990, however, the United States has been far more willing to employ unilateral economic sanctions to achieve other foreign policy objectives. During President Clinton's first term, U.S. laws and executive actions imposed new unilateral economic sanctions 61 times on a total of 35 countries.¹¹ These countries are home to 2.3 billion people, or 42 percent of the world's population, and purchase exports of $790 billion, or 19 percent of the global export market.

Congress and the President seem eager to impose additional unilateral economic sanctions this year. On May 20, for example, President Clinton issued an executive order determining that the "actions and policies of the Government of Burma constitute an unusual and extraordinary threat to the national security and foreign policy of the United States and declar[ing] a national emergency to deal with that threat." The order prohibited new investments in Myanmar.

In addition, Senator Arlen Specter (R-PA) and Representative Frank Wolf (R-VA) have introduced the Freedom from Religious Persecution Act of 1997 (S. 772 and H.R. 1685) to sanction countries that engage in religious persecution. The bill's findings demonstrate that its sponsors intend to apply the sanctions to many other countries: It specifically cites Cuba, Laos, the PRC, North Korea, and Vietnam as persecutors of Christians. It also alleges that Sudan and many other Islamic countries use blasphemy and apostasy laws both to prevent Muslims from converting to Christianity and to persecute Baha'i, Christian, and other religious minorities.

States and localities, emboldened by the apparent success of economic sanctions in fostering political change in South Africa, increasingly are imposing their own economic sanctions to satisfy the demands of vocal domestic constituencies. These sanctions typically are secondary boycotts mandating (1) procurement restrictions that prohibit the state or locality from buying goods and services from any firm doing business in a target country and (2) divestiture requirements to prevent the state or locality from investing public funds in any firm doing business in a target country. In the past two years, Massachusetts and a number of localities have enacted procurement restrictions targeting Myanmar.

This trend is spreading rapidly. Bills to sanction Switzerland for its banks' failure to return the secret deposits of Holocaust victims and families after World War II are pending before the New Jersey legislature and the city councils of Chicago and New York. Massachusetts and Rhode Island are considering sanctions against Indonesia for its actions in East Timor. New York City is considering economic sanctions against Cuba, China, Egypt, Indonesia, Kuwait, Laos, Morocco, North Korea, Pakistan, Sudan, and several former Soviet Republics for their alleged religious persecution of Christians.

All told, the explosive growth in the use of unilateral economic sanctions for other than national security purposes poses serious questions for Congress: Are unilateral U.S. economic sanctions worth the cost? Are there better ways to achieve the policy changes the U.S. government seeks in target countries?

Unilateral Sanctions: A Poor Track Record

Historically, unilateral economic sanctions have a poor track record in achieving national security and other foreign policy objectives. In a comprehensive study of all economic sanctions imposed worldwide between 1914 and 1990,¹² researchers found that economic sanctions failed to achieve their stated objectives in 66 percent of the 116 cases studied. The remaining cases, in which sanctions were at least partially successful, exhibited the following characteristics:

• The sender country was seeking a minor policy change in the target country, such as the release of a political prisoner, rather than a major policy reversal such as military withdrawal, a change in the head of government, or democratization.

• The sender country had a historic relationship with the target country, such as mother country to colony.

• The sender country's economy was strong and did not depend on trade and investment with the target country. In contrast, the target country's economy was very weak and depended heavily on trade and investment with the sender country.

• The sender country could isolate the target country internationally without much cooperation from other countries.

Yet even when all these conditions were present, the sender country seldom achieved an all-out victory; partial compliance was far more common.¹³ Moreover, the effectiveness of economic sanctions deteriorated over time; by 1990, the success ratio had fallen to 24 percent for all cases since 1973.¹⁴

Economic Sanctions in South Africa

Proponents cite South Africa as the prime example of how economic sanctions can foster democracy and respect for human rights. Most observers agree that international economic sanctions contributed to Pretoria's decision to free Nelson Mandela in February 1991, to enter into three years of negotiations with the African National Congress to end apartheid, to establish a new democratic constitution, and to hold South Africa's first free and fair election for a new Federal Parliament and nine provincial assemblies in April 1994. But even though these sanctions ultimately helped to undermine apartheid, they also took a long time to work.

In 1962, following the Sharpeville massacre, the U.N. adopted a voluntary multilateral arms embargo against South Africa. In 1977, the Security Council made the embargo mandatory. In 1978, Denmark, Norway, and Sweden established bilateral trade restrictions and prohibited new investment in South Africa. In 1986, the European Union and the United States imposed bilateral economic sanctions against South Africa. The members of the British Commonwealth of Nations imposed economic sanctions in 1988. In general, these sanctions restricted imports of certain agricultural and manufactured products, including gold Krugerrand coins (but not strategic minerals), from South Africa; banned exports of arms, nuclear material, and petroleum to South Africa; and prohibited new loans to or investments in South Africa.

By themselves, however, international economic sanctions were not enough to bring about political change. Several unique factors combined to buttress the adverse impact of these sanctions and undermine Pretoria's response:

• The racist character of apartheid isolated South Africa. Apartheid outraged blacks in the United States, the Caribbean, and sub-Saharan Africa. It also reminded many Europeans and Jews around the world of Nazism. Consequently, it generated widespread public opposition in Africa, Australia, Europe, and North America.

• South Africa lacked a sympathetic overseas emigrant community that could lobby their new homeland's government to support Pretoria. Most South Africans who emigrated to the United Kingdom, the United States, or other countries left because they opposed apartheid. They had little sympathy for the white minority regime in Pretoria.

• Non-governmental organizations played a crucial role. A coalition of civil rights, religious, and student organizations in Europe and North America known as the Free South Africa Movement mounted a disinvestment campaign. This campaign pressed large institutional investors, including university boards of trustees, state and local government pension fund managers, and charitable foundation directors, to liquidate all shares they held in corporations doing business with or investing in South Africa. The number of American corporations in South Africa fell from nearly 300 in 1980 to 104 in 1991.

Government-imposed international economic sanctions prohibited new loans to or investments in South Africa, but they did not require that banks call in existing loans or that corporations liquidate existing investments. In the end, it was the private decisions of commercial banks to go beyond what those sanctions required and call in existing loans to South Africa, along with the private decisions of corporate executives to liquidate their investments and stop doing business in South Africa, that produced the economic crisis that forced Pretoria to its knees.

The crucial event occurred on July 31, 1985, when Chase Manhattan Bank refused to renew $400 million in short-term loans. This decision provoked a financial crisis in South Africa. From 1985 to 1989, according to a U.S. General Accounting Office estimate, $10.8 billion flowed out of South Africa, including $3.7 in loan repayments and $7.1 billion in capital flight. Once private firms decided to stop doing business with South Africa, the economic pressure on Pretoria was irresistible.¹⁵

Why Unilateral Sanctions Can Be Counterproductive

As in the case of South Africa, multilateral economic sanctions may help to persuade a target country's government to change its objectionable policies under certain circumstances. Unilateral economic sanctions often fail to achieve their stated objective, however, and may sometimes be counterproductive.

Insufficient Penalty

Unilateral economic sanctions are not likely to place a sufficiently large financial burden on a target country's economy to persuade its government to change objectionable policies. There are very few industries in the United States that dominate the global market and are unchallenged by foreign rivals. Even for such sophisticated products as commercial satellites and supercomputers, the reality of foreign competition undermines the effectiveness of unilateral export restrictions. When the United States imposes a unilateral export embargo, foreign suppliers can replace the American companies with minimal damage to the target country's economy.

Unilateral economic sanctions frequently target countries that are autarkic or otherwise have minimal trade and investment ties to the United States, such as Myanmar and Vietnam. If target countries discourage international trade and investment in general, unilateral sanctions are unlikely to impose a significant financial burden on their governments; and even if they do penalize the target country, the penalty is usually small compared with the overall size of the country's economy. From 1914 to 1990, "[v]ery seldom did the costs of sanctions (expressed on anannualized basis) reach even 1 percent of a target country's GNP [gross national product]."¹⁶

Thus, the financial burden of unilateral U.S. economic sanctions is so small that it is highly unlikely to bring about the desired policy changes in the target country. Consider the 1980-1982 U.S. embargo on grain sales to the Soviet Union. Responding to the Soviet Union's invasion of Afghanistan, President Jimmy Carter imposed the embargo in January 1980 to "make the Soviets pay a price for aggression." Although U.S. allies and other members of the North Atlantic Treaty Organization (NATO) roundly condemned the invasion, the embargo was unilateral, reducing U.S. exports to the Soviet Union from an expected 25 million metric tons to 8 million metric tons (the amount required under pre existing commitments) in 1980. Nevertheless, the Soviet Union was able to expand its total grain imports from 31 million metric tons in 1979 to 40 million metric tons in 1982 because Argentine, Canadian, and European exports to the Soviet Union grew from 9.4 million metric tons to 23 million metric tons over the same period.¹⁷

The Soviet Union paid only $225 million in higher grain prices due to the embargo, compared with an estimated loss of $2.3 billion in foregone grain exports to American farmers. In 1981, President Ronald Reagan lifted the grain embargo because "it was not having the intended effect of seriously penalizing the USSR for its brutal invasion and occupation of Afghanistan."¹⁸

Counterproductive

Even worse, unilateral economic sanctions often prove counterproductive by undermining a target country's emerging middle class rather than its political leaders. In many countries, including Chile, South Korea, Taiwan, and Thailand, the development of a large, financially secure middle class was necessary before their authoritarian governments could give way to democracy. Unilateral U.S. economic sanctions strike hardest at Western-educated business managers and professionals who interact most often with the rest of the world and who are the most amenable to foreign influence. By hammering the international sector of a target country's economy, unilateral sanctions may retard the growth of a middle class and thereby slow the process of democratization.

When the United States imposes unilateral economic sanctions not on rogue countries like Iran and Libya, but on friendly countries like Mexico, broader foreign policy interests can be damaged. The United States needs Mexican cooperation on a wide variety of bilateral problems including illegal immigration, drug trafficking, and cross-border pollution control. Disrupting relations with Mexico by imposing unilateral economic sanctions for any one issue, however serious, risks a populist backlash against the United States with consequent repercussions for the resolution of other equally important border problems.

Leadership Fallacy

Proponents argue that the United States must display moral leadership by being the first to impose unilateral economic sanctions, after which other countries, sensing U.S. leadership, will jump on board and support multilateral economic sanctions. Recent history, however, demonstrates otherwise. Instead of following U.S. leadership, other countries see unilateral U.S. economic sanctions as commercial opportunities to grab lucrative foreign markets from American companies.

The United States still maintains the economic sanctions it imposed against China after the Tiananmen Square massacre in 1989. The European Union and Japan lifted theirs within a few months. Consequently, while the United States continues to enforce its unilateral embargo on nuclear technology exports, European and Japanese companies have sold $15 billion in nuclear power technology to China. Because of the U.S. embargo, Westinghouse, a world leader in the nuclear power industry, has been forced to lay off 3,500 American workers.¹⁹

To pressure the military junta in Myanmar to end its human rights abuses, the United States encouraged the members of the Association of Southeast Asian Nations (ASEAN) to delay granting membership to Myanmar and to support comprehensive multilateral economic sanctions against it. ASEAN's two most vigorous democracies, the Philippines and Thailand, initially were reluctant to approve Myanmar's application. Even Singapore Prime Minister Goh Chok Tong suggested that Myanmar should wait until its government was "more normal." On May 20, 1997, however, President Clinton acted unilaterally and imposed a prohibition on new investment in Myanmar. The ASEAN leaders reacted angrily. President Suharto of Indonesia especially feared that Clinton's action might set a precedent for unilateral economic sanctions against his own country because of its suppression of the independence movement on East Timor. Consequently, on May 31, President Suharto and the other ASEAN leaders defied the United States and invited Cambodia, Laos, and Myanmar to join ASEAN at an upcoming July 1997 summit in Malaysia.²⁰

Wary of growing Chinese influence in Myanmar, ASEAN leaders fear that Myanmar might provide air and naval bases to the PRC. Through economic and political engagement, they are seeking to wean Myanmar away from the PRC. Thus, while unilateral U.S. economic sanctions prevent new U.S. investment, Japan, Singapore, and other Southeast Asian countries are pouring funds into Myanmar. The only country that is being isolated by unilateral U.S. economic sanctions against Myanmar is the United States itself.

The High Cost of Economic Sanctions

Even though the ability of unilateral U.S. economic sanctions to engender desired policy changes in target countries is doubtful at best, their high and mounting cost to the U.S. economy is not. When the United States imposes unilateral sanctions, there is an immediate cost to American companies and their employees in terms of lower exports and overseas investment and fewer jobs. This, however, is only a small portion of the total damage that unilateral economic sanctions do to the U.S. economy. Even after they are lifted, it takes years (assuming they can do so at all) for American companies to recover the market share lost to foreign rivals in a target country while the sanctions were in force.

Immediate Costs

In a study of the economic impact of all U.S. economic sanctions, Gary Clyde Hufbauer, Kimberly Ann Elliott, Tess Cyrus, and Elizabeth Winston found that sanctions "reduced exports to 26 target countries by as much as $15 billion to $19 billion in 1995.É [T]hat would mean a reduction of more than 200,000 jobs in relatively higher-wage export sector and a consequent loss of nearly $1 billion annually in export sector wage premiums."²¹ In 1994, a more limited study of the economic impact of sanctions by the Council on Competitiveness found that eight specific sanctions cost the U.S. economy $6 billion in annual export sales and 120,000 export-related jobs.²²

Long-Term Costs

The cost of unilateral economic sanctions to the U.S. economy goes far beyond initial lost sales. Frequently, the initial sale may be only the beginning of economic transactions between American exporters and their foreign customers. Initial sales of construction equipment, computer systems, and other capital goods often are followed by related sales of service contracts, upgrades, and replacement parts. Because of lost follow-on sales and services, unilateral economic sanctions may reverberate through the U.S. economy for many years after they are lifted.

In addition, reentering a market after sanctions are lifted is costly and can take decades. When U.S. economic sanctions are unilateral, European and Japanese rivals replace American suppliers and develop long-term customer relationships. Once sanctions are lifted, customers are unlikely to abandon well-established, satisfactory relationships with these suppliers just because American companies have reentered the market. To overcome lingering distrust, American companies may be forced to cut prices, transfer technology, or make concessions that they otherwise would not grant.

Economic sanctions can be particularly damaging for suppliers of aircraft, construction equipment, and motor vehicles that are purchased and maintained as fleets. Many corporate customers prefer to use a single fleet supplier to lower the servicing and replacement parts costs. Consequently, once a corporate customer has chosen a supplier, competing suppliers may not be able to sell to that customer. Boeing experienced this problem in 1993 because of the U.S. trade embargo against Vietnam. Vietnam Airlines hoped to lease six narrow-body, medium-range aircraft from Boeing but chose to lease Airbus A320 aircraft instead when the embargo was not lifted. The initial loss to Boeing was $211 million. Moreover, having built its maintenance and training programs around Airbus, Vietnam Airlines has continued to lease A320s despite the lifting of the embargo and plans to acquire a total of 30 A320s by the year 2000, bringing Boeing's total loss to $1.6 billion.²³

Lost Confidence

Unilateral U.S. economic sanctions have a long-term corrosive effect on trust between American companies and their foreign customers even in countries not subject to sanctions. Customers need to know that customer-supplier contracts will be honored. The growing tendency for the United States to impose unilateral economic sanctions in cases in which there is no clear national security issue at stake undermines the reliability of American companies.

U.S., European, and Japanese exports to China were roughly equal in 1990. Since that time, European exports have grown 1.5 times as fast as U.S. exports, and Japanese exports have grown twice as fast. Greg Mastel of the Economic Strategy Institute attributes this difference to unilateral economic sanctions:

First, the United States has held up export financing to China and barred China from many of its aid programs. Meanwhile, Japan and Europe have aggressively and generously extended both of these programs to China.... A second factor contributing to weak U.S. export performance has been the ongoing political tension between the United States and China.²⁴

Even in friendly countries, the fear of U.S. sanctions is causing high technology customers to redesign their products to minimize the number of U.S. made components whenever possible. For example, Airbus's first commercial jet contained over 50 percent U.S.-made components. To escape the reach of U.S. export controls, Airbus reduced its U.S.-made parts content to below 20 percent.²⁵

Reduction of Foreign Direct Investment

Inward foreign direct investment is increasingly important to the U.S. economy. In 1995, inward foreign direct investment in the United States totaled $561 billion, and U.S. subsidiaries of foreign companies employed 4.9 million Americans.²⁶ In today's global economy, manufacturing plants do not just supply the domestic market of the country in which they are located; they must serve as an export platform for markets around the world. Consequently, the prospect that Washington, D.C., might impose unilateral export restrictions at some time in the future discourages multinational firms from opening new production and distribution facilities within the United States, and this translates to fewer jobs for American workers.

Dangers of State and Local Economic Sanctions

The success of the Free South Africa Movement in persuading states and localities to impose unilateral economic sanctions against South Africa has caused other constituencies to lobby state legislatures, county boards, and city councils across the United States to sanction countries for objectionable policies. Because states and localities cannot influence foreign governments through primary boycotts (for example, a decision by state or local government not to procure goods and services from or invest public funds in a targeted country), they attempt to influence them indirectly through secondary boycotts of two types: (1) procurement restrictions that bar any company that does business in a target country from supplying goods and services to the state or locality and (2) investment restrictions that prevent a state or locality from investing public funds in or lending public funds to any company that does business in a target country. Like the Arab League boycott of Israel, these sanctions attempt to force companies to choose between doing business with the state or local government or doing business in the target country.

The most recent target is Myanmar; and although they have been confined only to Massachusetts and a few U.S. cities, the sanctions already have had some effect. Apple Computer, Philips Electronics, Amoco, Columbia Sportswear, Carlsberg, Levi Strauss, Liz Claiborne, and Spiegel's Eddie Bauer left Myanmar before President Clinton imposed his unilateral prohibition on new investment in May.²⁷ These state and local economic sanctions, however, raise important practical and constitutional issues.

Incoherence and Disunity

Economic sanctions are serious foreign policy tools, and their application can impose great dislocation costs at home and harmful diplomatic consequences abroad. Congress and the President have access to a wide range of information on foreign affairs. They must use such information to weigh a variety of competing U.S. interests before applying economic sanctions. State and local officials, on the other hand, are ill-equipped to evaluate the possible ramifications of sanctions and tend to view a sanctions bill as a cheap way to please vocal domestic constituencies.

Unilateral state and local sanctions can interfere with the making of foreign policy and prevent the United States from speaking with one voice on international issues. They also may limit the ability of the United States to respond to positive changes in a target country and force American companies to choose between domestic markets and growing international markets, thereby threatening both exports and jobs. State and local governments do not have to deal with the diplomatic and economic effects of such actions, but Congress and the President must cope with the unintended consequences of unilateral state and local economic sanctions.

Dubious Constitutionality

Beyond these practical questions, attorneys David Schmahmann and James Finch allege that unilateral state and local economic sanctions are unconstitutional on at least two grounds.²⁸

First, Article I, Section 8, Clause 3 of the U.S. Constitution prohibits states and localities from regulating or taxing commerce if such actions unduly burden interstate or foreign commerce. The Supreme Court has long held that the federal government has the exclusive power to regulate foreign commerce.²⁹ In Japan Line Ltd. v. County of Los Angeles, the Supreme Court found that "Foreign commerce is preeminently a matter of national concern. `In international relations and with respect to foreign intercourse and trade the people of the United States speak with one voice through a single government with unified and adequate national power.'"³⁰

Proponents have countered that state and local governments can impose sanctions under the market participant doctrine, a principle allowing a state or local government to favor the preferences of its own citizens when buying or selling goods and services as a market participant rather than as a regulator. The Supreme Court, however, never has applied this doctrine to foreign commerce. In fact, in South-Central Timber Development v. Wunnicke, the Supreme Court overturned-specifically because it impinged on foreign commerce-an Alaska law requiring that all timber sold from certain state-owned parcels be processed within the state.³¹

Second, Article 6, Section 2 provides for the supremacy of federal laws and treaties. In Hines v. Davidowitz, the Supreme Court struck down a Pennsylvania law that imposed different and far more onerous registration requirements on aliens than required under federal law. The Supreme Court found that, in international relations, "[a]ny concurrent state power that may exist is restricted to the narrowest of limits."³² Moreover:

The Federal Government, representing as it does the collective interests of the forty-eight states, is entrusted with full and exclusive responsibility for the conduct of affairs with foreign sovereignties. For local interests the several States of the Union exist, but for national purposes, embracing our relations with foreign nations, we are but one people, one nation, one power. Our system of government is such that the interests of cities, counties, and states, no less than the interests of the people of the whole nation imperatively requires that federal power in the field affecting foreign relations be left entirely free from local interference.³³

If unilateral state and local economic sanctions are so clearly unconstitutional, one might wonder why businesses harmed by them have not brought suit in federal court. Companies have demurred from filing suit because no one wants to be identified publicly with such actions as seeming to defend apartheid in South Africa or the State Law and Order Restoration Council regime in Myanmar. Even if private citizens hesitate, however, Congress and the President must act because these sanctions pose a serious threat to the unity and coherence of U.S. foreign policy.
