The World Trade Organization (WTO) was established in 1995 to oversee international trade. It has 164 member countries, including India. The WTO aims to establish rules for trade, provide a forum for negotiations, settle disputes, and offer technical assistance to developing nations. It is headed by the biennial Ministerial Conference and managed by the General Council. Key principles of the WTO include non-discrimination, most favored nation status, national treatment, reciprocity, transparency, and encouraging development. Important agreements under the WTO cover agriculture, intellectual property, sanitary and phytosanitary standards, technical barriers to trade, trade-related investment measures, and services.
