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
Brazil has received backing from 3 of the current permanent members, namely France, Russia, and the United Kingdom. Brazilian elevation to permanent membership is also supported by the Community of Portuguese Language Countries (CPLP), and Brazil and the other G4 nations mutually support each other in their bids. Other countries that advocate permanent Brazilian membership of the UNSC include Australia, Chile, Finland, Guatemala, Indonesia, the Philippines, Slovenia, South Africa, and Vietnam
