The World Trade Organization (WTO), established on January 1, 1995, oversees global trade relations through agreements signed by member nations, promoting fair trade practices and reducing barriers. It evolved from the General Agreement on Tariffs and Trade (GATT) and consists of 162 member states, with a focus on goods, services, and intellectual property. The organization's dispute settlement system and ongoing trade negotiations, particularly the Doha Development Round, address complex trade issues and encourage cooperation among nations.
