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.
Reform of the United Nations Security Council
India's bid for permanent member of UNSC is now backed by four of the five permanent members, namely France, Russia, United Kingdom and United States. On 15 April 2011, China officially expressed its support for an increased Indian role at the United Nations, without explicitly endorsing India's Security Council ambitions. A few months later, China endorsed Indian candidacy as a permanent UNSC member provided that India revokes its support for Japanese candidacy.
