The document summarizes the historical evolution of the General Agreement on Tariffs and Trade (GATT) and the establishment of the World Trade Organization (WTO). It discusses that GATT was created in 1947 as a provisional agreement but became the foundation of global trade rules. The WTO was established in 1995 after the Uruguay Round negotiations to provide more structure and enforceable rules for international trade.
