The World Trade Organization (WTO), established on January 1, 1995, regulates international trade among its 164 member states to ensure smooth, predictable, and free trade. Its main functions include administering trade agreements, resolving disputes, and promoting sustainable development and economic growth. The WTO operates through various bodies, such as the Ministerial Conference and the Dispute Settlement Body, and is involved in several trade agreements, including those on agriculture and intellectual property.
