The original Bretton Woods conference called for the creation of three international organizations. While the IMF and the World Bank were created shortly after the conference, an international organization devoted to the facilitation of international trade was only created in 1996, when the World Trade Organization (WTO) was established incorporating the General Agreement on Tariffs and Trade (GATT). While the IMF cooperates with a large number of international organizations, including all the regional development banks, the common origin and complementary mandates of the IMF, World Bank, and WTO led to intense and well-defined forms of cooperation.
