Good Neighbor Policy and trade

In December 1933, Roosevelt signed the Montevideo Convention on the Rights and Duties of States, renouncing the right to intervene unilaterally in the affairs of Latin American countries. After the withdrawal of U.S. forces from Haiti, the only U.S. military forces remaining in the Caribbean were stationed in the Panama Canal Zone and the Guantanamo Bay Naval Base. In 1934, Congress enacted Cordell Hull 's key program, the Reciprocal Tariff Act. It allowed the president to negotiate trade reciprocity treaties with other countries. Over the next six years, the U.S. signed agreements with 21 countries, primarily in Latin America. resulting in a significant reduction of tariff levels. Thanks to the reciprocal tariffs and the new Export–Import Bank, trade between the U.S. and Latin America more than tripled between 1931 and 1941.
