Although the world has changed dramatically since the FDR passed the Mutual Trade Agreements Act, the basic trade promise remains the same. Well done, trade policy gives American workers the chance to compete in a level playing field, and under the TPA, Congress and the government unite to manage trade with global partners by setting goals and standards that defend American interests and values. Between 1934 and 1945, the United States signed 32 reciprocal trade agreements with 27 countries.  In addition, the conclusion of the General Agreement on Tariffs and Trade was taken by the Authority under the RTAA. The Trade Promotion Authority aims to create opportunities for domestic workers, just as Roosevelt`s RTAA supported job creation on the national territory through trade in New Deal programs. The TPA is an important element of trade negotiations because it allows Congress to define the terms of trade negotiations, consultations at Congress during negotiations and legislative procedures for voting on agreements. The U.S. State Department also found good use of free trade expansion after World War II. Many in the Department of Foreign Affairs saw multilateral trade agreements as a means of integrating the world in accordance with the Marshall Plan and the Monroe Doctrine. U.S. trade policy has become an integral part of U.S.
foreign policy. This search for free trade as diplomacy intensified during the Cold War, when the United States competed with the Soviet Union for relations around the world.  Democrats voted far more in favor of trade liberalization than Republicans, but were not consistent in their preferences. Mp Henry Rainey (D-IL) and members of Roosevelt`s government, Rexford Tugwell, Raymond Moley and Adolf Berle, were skeptical of tariff reductions during the Depression. However, the government decided to use a Democratic-controlled congress and presidency to impose the RTAA. In 1936 and 1940, the Republican Party ran on a platform to lift tariff reductions guaranteed under the RTAA. But when they reclaimed Congress in 1946, they did not act to remove tariffs. In the years since the adoption of the RTAA in 1934, the economies of Europe and East Asia had been decimated by the violence of World War II, which left a huge global production gap filled by American exporters.
 During the war, the United States had the highest positive balance in its history. Republican preferences for tariffs began to shift as exporters in the home districts began to benefit from stronger international trade. In the 1950s, there was no statistically significant difference between Republicans and Democrats on customs policy, a change that has lasted ever since.  Eighty years later, the tradition of the Mutual Trade Agreements Act continues in the form of the modern Trade Promotion Authority (TPA).
