RTAA meaning in Governmental ?

The Reciprocal Tariff Act (enacted June 12, 1934, ch. 474, 48 Stat. 943, 19 U.S.C. § 1351) provided for the negotiation of tariff agreements between the United States and separate nations, particularly Latin American countries. The Act served as an institutional reform intended to authorize the president to negotiate with foreign nations to reduce tariffs in return for reciprocal reductions in tariffs in the United States up to 50%. It resulted in a reduction of duties. This was the policy of the low tariff Democrats in response to the high tariff Republican program which produce the Hawley Smoot tariff of 1930 that raised rates, and sharply reduced international trade. The Reciprocal Tariff Act was promoted heavily by Secretary of State Cordell Hull.
