United Nations Security Council
The Security Council consists of fifteen members. The great powers that were the victors of World War II—the Soviet Union (now represented by Russia), the United Kingdom, France, China, and the United States—serve as the body's five permanent members. These permanent members can veto any substantive Security Council resolution, including those on the admission of new member states or candidates for Secretary-General. The Security Council also has 10 non-permanent members, elected on a regional basis to serve two-year terms. The body's presidency rotates monthly among its members.
United Nations Economic and Social Council
The United Nations Economic and Social Council (ECOSOC; , ) is one of the six principal organs of the United Nations, responsible for coordinating the economic, social, and related work of 15 UN specialized agencies, their functional commissions and five regional commissions. The ECOSOC has 54 members. The General Assembly selects 18 new members for ECOSOC each year for the term of 3 years with a provision that a retiring member can be re-elected. It holds one seven-week session each year in July, and since 1998, it has also held an annual meeting in April with finance ministers heading key committees of the World Bank and the International Monetary Fund (IMF).
