The document provides a history of the General Agreement on Tariffs and Trade (GATT) and the World Trade Organization (WTO) system. It discusses that GATT was created in 1947 to govern international trade and underwent various negotiating rounds to reduce tariffs. Problems with GATT emerged in the 1980s which led to the Uruguay Round and establishment of the WTO in 1995 to address these issues and expand the rules-based trading system. Key principles of GATT/WTO include reciprocity in trade negotiations, non-discrimination, and predictability in trade relations.
