The World Trade Organization (WTO) was established in 1995 to provide rules and a forum for negotiating international trade agreements. It grew out of the General Agreement on Tariffs and Trade (GATT) established in the 1940s. The WTO aims to reduce trade barriers through negotiation rounds and provides a dispute settlement process to resolve conflicts between members. It also establishes principles of non-discrimination in trade and provides constraints on members' trade policies. While aiming to benefit all members, decisions are often dominated by large, wealthy countries.
