When the Dillon cycle went through the laborious process of collective bargaining by post, it became clear, well before the end of the cycle, that a more comprehensive approach was needed to address the emerging challenges arising from the creation of the European Economic Community (EEC) and EFTA, as well as to make Europe a major international distributor in general. However, this part of the result was not authorized by Congress and the U.S. selling price was not abolished until Congress passed the results of the Tokyo Round. The results in agriculture as a whole have been poor. The most notable achievement was the agreement on a Memorandum of Understanding on the basic elements for the arrangement of global subsidies, which was eventually incorporated into a new international agreement on cereals. The GATT came into force on January 1, 1948. From the beginning, it was refined, which eventually led to the creation, on 1 January 1995, of the World Trade Organization (WTO), which absorbed and expanded it. To date, 125 nations signed its agreements, which covered about 90% of world trade. That is, quantitative barriers to trade, such as trade controls and quotas.
The agreement also provided for a system for resolving trade disputes between nations and the framework allowed for a series of multilateral negotiations on the removal of customs barriers. The GATT was considered a major success in the post-war years. The Uruguay Round Agricultural Agreement remains the most important agreement in the history of trade negotiations for the liberalisation of agricultural trade. The aim of the agreement was to improve market access for agricultural products, reduce national aid to agriculture in the form of price-distorting subsidies and quotas, eliminate agricultural export subsidies over time and harmonize health and plant health measures among Member States as much as possible. Following the UK`s vote to leave the European Union, proponents of leaving the European Union proposed that Article 24, paragraph 5B of the treaty could be used to maintain a “stalemate” in trade conditions between the UK and the EU if the UK left the EU without a trade deal, thereby preventing the imposition of tariffs. Proponents of this approach believe that it could be used to implement an interim agreement until a final agreement of up to ten years is negotiated.  In addition to facilitating tariff reductions, GATT`s contribution to trade liberalization involves “the commitment of tariff reductions negotiated for a longer period (which became more sustainable in 1955), the definition of the universality of non-discrimination through the treatment of the most favoured nation (MFN) and the status of national treatment, the guarantee of greater transparency of trade measures and the creation of a forum for future negotiations and settlement bilateral disputes.
