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.
Eastern European Group
The Eastern European Group has two seats in the United Nations Security Council (UNSC); the permanent seat of Russia, and one elected seat, currently held by Ukraine. The Group further has 6 seats on the United Nations Economic and Social Council and 6 seats on the United Nations Human Rights Council. It is also eligible for having its nationals elected as President of the United Nations General Assembly in years ending with 2 and 7; most recently, Vuk Jeremić of Serbia was elected to this position in June 2012 and was the office holder of the Sixty-seventh session.
