Permanent members of the United Nations Security Council
The permanent members of the United Nations Security Council (also known as the Permanent Five, Big Five, or P5) are the five states which the UN Charter of 1945 grants a permanent seat on the UN Security Council: China (formerly the Republic of China), France, Russia (formerly the Soviet Union), the United Kingdom, and the United States. These countries were all allies in World War II, which they won. They are also all nuclear weapons states. A total of 15 UN member states serve on the UNSC, the remainder of which are elected. Any one of the five permanent members have the power of veto, which enables them to prevent the adoption of any "substantive" draft Council resolution, regardless of its level of international support.
G4 nations
The UN currently has five permanent members with veto power in the Security Council: China, France, Russia, the United Kingdom, and the United States- comprising the victors of World War II. The G4 nations are regularly elected to two-year terms on the Security Council as non-permanent members by their respective regional groups: in the 24-year period from 1987 to 2010, Brazil and Japan were elected for five terms each, Germany for four terms (one term as West Germany and three terms as unified Germany) and India for four terms. Cumulatively, the G4 has spent 64 years on the Security Council since the UN's inception, with each country serving at least a decade. By comparison, the three permanent members of the Security Council who have maintained their seats since the UN's founding (France, the UK, and the US) have each accrued years of membership. The People's Republic of China has held its permanent seat for years, since it replaced the Republic of China in 1971, and Russia has held its permanent seat for years, since it replaced the Soviet Union in 1991.
