President Franklin D. Roosevelt signed the Reciprocal Trade Agreements Act (RTAA) in 1934. It gave the president the power to negotiate bilateral and reciprocal trade agreements with other countries and allowed Roosevelt to liberalize U.S. trade policy around the world. It is generally attributed that it sounded the era of liberal trade policy that continued during the 20th century.  In negotiating agreements under the RTAA, the United States has generally made direct concessions only to so-called primary suppliers, namely countries that were or are likely to become the main source or important source of supply for the product in question. The concessions were granted in exchange for opening foreign markets to U.S. exports. 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. As more and more U.S.
industries began to benefit from tariff cuts, some of them began campaigning with Congress for lower tariffs. Until RTAA, Congress had been mainly pressured by industries that wanted to create or increase tariffs to protect their industry. This change has also helped to maintain many of the benefits of trade liberalization. In short, the political incentive to increase tariffs has diminished and the political incentive to reduce tariffs has increased.  The Reciprocal Tariff Act (which came into force on June 12, 1934, Chapter 474, 48 Stat. 943, 19 U.S.C No. 1351) provided for the negotiation of customs agreements between the United States and various nations, including Latin American countries.  The law served as an institutional reform to allow the president to negotiate with foreign nations a reduction in tariffs in exchange for a reciprocal reduction in U.S. tariffs. This has led to a reduction in tariffs.
From there, the President was granted, during the rounds and negotiations on the free trade area at the GATT (later the WTO), the negotiating powers of non-tariff measures in the respective legislation, such as the Trade Act of 1974, but the power to reduce tariffs was generally similar to that of the RTAA. The Reciprocal Trade Agreements Act was signed on June 12, 1934 as part of the Roosevelt administration`s efforts to pull America out of the Great Depression. RTAA has been an integral step in the U.S. transition from economic crisis to global leadership. The FDR considered that a full and sustainable recovery depended on strengthening international trade to increase domestic growth and demand. To ensure our country`s place in the global economy, the U.S. President and Congress had to work together to negotiate trade agreements, reduce tariffs on goods and increase U.S. exports.
Strengthening international trade fostered the growth aspects of the New Deal`s domestic programs, and the successful implementation of the RTAA resulted in the conclusion of 19 new trade agreements between 1934 and 1939, strong growth in U.S. exports and a recovery of the U.S. economy. RTAA`s innovative approach freed Roosevelt and Congress from breaking this trend of tariff increases. It has linked U.S. tariff reductions to reciprocal tariff reductions with international partners. It also allowed Congress to approve tariffs by a simple majority, unlike the two-thirds majority needed for other contracts. In addition, the President had the power to negotiate the terms.
The three innovations in trade policy have created the political will and feasibility of a more liberal trade policy.  Secretary Hull`s initial efforts were to reach reciprocal trade agreements
