The creation of WTO marked a big and important change in the international trade and represented one of the biggest reforms after the Second World War.It aimed to regulate the international trade in the most suitable and fair manner for all the countries members.
Much of the history of those 47 years was written in Geneva. But it also traces a journey that spanned the continents, from that hesitant start in 1948 in Havana (Cuba), via Annecy (France), Torquay (UK), Tokyo (Japan), Punta del Este (Uruguay), Montreal (Canada), Brussels (Belgium) and finally to Marrakesh (Morocco) in 1994. During that period, the trading system came under GATT, salvaged from the aborted attempt to create the ITO. GATT helped establish a strong and prosperous multilateral trading system that became more and more liberal through rounds of trade negotiations. But by the 1980s the system needed a thorough overhaul. This led to the Uruguay Round, and ultimately to the WTO.
GATT: ‘provisional’ for almost half a century
From 1948 to 1994, the General Agreement on Tariffs and Trade (GATT) provided the rules for much of world trade and presided over periods that saw some of the highest growth rates in international commerce. It seemed well-established, but throughout those 47 years, it was a provisional agreement and organization.
The original intention was to create a third institution to handle the trade side of international economic cooperation, joining the two “Bretton Woods” institutions, the World Bank and the International Monetary Fund. Over 50 countries participated in negotiations to create an International Trade Organization (ITO) as a specialized agency of the United Nations. The draft ITO Charter was ambitious. It extended beyond world trade disciplines, to include rules on employment, commodity agreements, restrictive business practices, international investment, and services. The aim was to create the ITO at a UN
