Agriculture has been essentially excluded from previous agreements, as it has been granted special status in the areas of import quotas and export subsidies, with slight reserves. However, at the time of the Uruguay Round, many countries considered the agricultural exception so egregious that they refused to sign a new no-move agreement for agricultural products. These fourteen countries were known as the “Cairns Group” and consisted mainly of small and medium-sized agricultural exporters such as Australia, Brazil, Canada, Indonesia and New Zealand. This statement served as the basis for the so-called “Malthouse Compromise” between conservative parties on how to replace the withdrawal agreement.  However, this plan was rejected by Parliament.  The assertion that Article 24 could be used was also adopted by Boris Johnson during his 2019 campaign as leader of the Conservative Party. The fourth round returned to Geneva in 1955 and lasted until May 1956. 26 countries participated in the cycle. $2.5 billion in tariffs have been eliminated or reduced. THE GATT and its successor, the WTO, have succeeded in reducing tariffs.
Average tariff levels for large GATT participants were about 22% in 1947, but were 5% after the Uruguay Round of 1999.  Experts attribute some of these tariff changes to the GATT and the WTO.    WTO decisions on the GATT agreement are made in the WTO`s Analytical Evidence guide to law and practice The third round took place in Torquay, England, in 1951.   38 countries participated in the cycle. 8,700 tariff concessions were granted for the remaining tariff on three-fourth of the tariffs that came into effect in 1948. The simultaneous rejection of the Havana Charter by the United States meant the creation of the GATT as a global federation.  The summit almost resulted in a third organization. This should be the very ambitious International Trade Organization (ITO). The 50 countries that started negotiations wanted an agency within the United Nations to create rules, not only for trade, but also for jobs, agreements on raw materials, trade practices, foreign direct investment and services.
The ITO charter was adopted in March 1948, but the U.S. Congress and a few other countries refused to ratify it. In 1950, the Truman administration declared defeat and completed the ITO. In 1965, the third provision was addressed to developing countries that join the GATT. Developed countries have agreed to eliminate tariffs on imports from developing countries in order to stimulate these economies.
