Geographic proximity has forged strong linkages between the United States and the nations of Latin America and the Caribbean, with critical U.S. interests in the region encompassing economic, political, and security concerns. U.S. policymakers have emphasized different strategic interests in the region at different times, from combating Soviet influence during the Cold War to advancing democracy and open markets since the 1990s. Current U.S. policy toward the region is designed to promote economic and social opportunity; ensure citizen security; strengthen effective democratic institutions; and secure a clean energy future. As part of broader efforts to advance these priorities, the United States provides Latin American and Caribbean nations with substantial amounts of foreign assistance. Congress - which authorizes and appropriates aid for the region, and engages in oversight of assistance programs - is currently considering the President's foreign aid request for FY2013. In recent years, the State Department, Foreign Operations, and Related Programs appropriations measure has been the primary legislative vehicle through which Congress reviews U.S. assistance and influences executive branch policy toward the region.
