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.  Between 1934 and 1939, the Roosevelt administration concluded trade agreements with 19 countries under the Reciprocal Trade Agreements Act: Belgium, Brazil, Canada, Colombia, Costa Rica, Cuba, Czechoslovakia, Ecuador, El Salvador, Finland, France, Guatemala, Haiti, Honduras, the Netherlands, Nicaragua, Sweden, Switzerland and the United Kingdom. After 1945, the customs negotiation procedure established under the RTAA programme formed the model of the General Agreement on Tariffs and Trade (GATT), the agreement signed in 1947 by 23 countries, which formed the framework for multilateral trade liberalization after the Second World War. 2.
States that the main negotiating objectives of the United States in improving the WTO and multilateral trade agreements are to improve the functioning and extension of the scope of the WTO and these agreements to products, sectors and trade conditions that are not adequately covered; and (2) to extend, if necessary, countries` participation in certain agreements. 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.  states that bills on the implementation of trade agreements may only be eligible for approval of fast-track trade agreements in Congress if they consist exclusively of the following provisions, which approve a trade agreement concluded pursuant to that Act, which achieves one or more of the main objectives of the above negotiations, and approve any declaration of administrative measures; 2. provisions that are necessary for the implementation of such an agreement or which are linked, by other means, to the implementation, implementation and adaptation of the effects of this trade agreement and which are directly related to trade; and (3) the provisions necessary to meet the requirements of the Gramm-Rudman-Hollings Act 1985 for balanced budgets and the fight against the state of emergency.
Provides for the extension of expedited procedures to agreements reached on 1 October 2001 or after 1 October 2001 and before 1 October 2005, at the request of the President, if neither of the two members of Congress adopts a resolution rejecting the extension under a defined procedure. 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.
