After the Great Depression, the country emerged as among the most significant global trade policy-makers, and it is now a partner to a number of international trade agreements, including the General Agreement on Tariffs and Trade (GATT) and the World Trade Organization (WTO). Gross U.S. assets held by foreigners were $16.3 trillion as of the end of 2006 (over 100% of GDP). Foreign trade is nothing but trade between the different countries of the world. It is also called as International trade, External trade or Inter-Regional trade. It consists of imports, exports and entrepot. The United States pursues its four main foreign policy goals through several different foreign policy types, or distinct substantive areas of foreign policy in which the United States is engaged. These types are trade, diplomacy, sanctions, military/defense, intelligence, foreign aid, and global environmental policy.
