The most straightforward and preferable path to trade liberalization for any country is the unilateral reduction of trade barriers without regard for other countries’ trade policies. Unilateral liberalization allows a country to realize the gains from openness—mainly lower prices for consumers, lower-cost inputs for businesses, and a more favorable exchange rate for exporters—without the need for complicated negotiations with other countries. Many nations have followed this route with success, from Great Britain in the mid–19th century to China and India and other emerging economies since the 1980s. As discussed in a separate Defending Globalization essay, however, unilateral liberalization is politically difficult, so governments have turned to reciprocal trade agreements, which offer reduced trade barriers at home in exchange for similar liberalization among participating governments abroad. The best approach to trade agreement liberalization is multilateral—the lowering of barriers to goods, services, and investment in a nondiscriminatory way by almost all countries through such forums as the World Trade Organization (WTO). A next-best option is bilateral and regional FTAs among two or several governments, respectively.
The United States is a partner in bilateral and regional FTAs with 20 other nations, including such major trading partners as Canada, Mexico, South Korea, Singapore, and Australia (Figure 1). The United States was a founding member of the General Agreement on Tariffs and Trade after World War II and is a member of its successor institution, the WTO, a multilateral agreement with 165 other countries that covers 98 percent of world trade. The United States is also party to narrower bilateral investment treaties with about 40 other nations that protect American investment assets abroad.
