United Nations System
There are 15 members of the Security Council, consisting of five veto-wielding permanent members (China, France, Russia, the United Kingdom, and the United States) and 10 elected non-permanent members with two-year terms. This basic structure is set out in Chapter V of the UN Charter. Security Council members must always be present at UN headquarters in New York so that the Security Council can meet at any time.
1988 United Nations Security Council election
The Security Council has 15 seats, filled by five permanent members and ten non-permanent members. Each year, half of the non-permanent members are elected for two-year terms. A sitting member may not immediately run for re-election.
