The General Agreement on Tariffs and Trade (GATT) was created in 1947 and operated almost five decades on a provisional basis until 1995 when the WTO was established. Its goal is to improve the welfare of peoples of its member countries, specifically by lowering trade barriers and providing a platform for the negotiation of trade. The organization deals with the rules of trade between nations at a global or near global level; it is responsible for negotiating and implementing new trade agreements and charged with policing Member Countries' adherence to all WTO agreements. In 2007 there were 150 Member States.
