The World Trade Organization (WTO) was established in 1995 to oversee global trade rules and liberalize trade. It grew out of the General Agreement on Tariffs and Trade (GATT) established in 1948. The WTO has 161 member countries and its headquarters are in Geneva, Switzerland. Its main objectives are to support member countries in expanding trade across borders according to agreed upon trade agreements. It plays an important role in promoting fair and smooth international business by helping to resolve trade disputes, lowering trade barriers through negotiation, and stimulating economic growth.
