The document provides a history and overview of the General Agreement on Tariffs and Trade (GATT) and its evolution into the World Trade Organization (WTO). It discusses that GATT was established in 1947 to promote international trade and reduce trade barriers. Key aspects of GATT included non-discrimination principles and prohibiting quantitative trade restrictions. GATT was then transformed into the WTO in 1995 which established a stronger institutional framework with agreements covering trade in goods, services, and intellectual property. The WTO operates through a hierarchical structure with ministerial conferences and councils overseeing areas like trade in goods, services, and dispute settlement. Decision-making aims to be consensus-based.
