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.
Reform of the United Nations Security Council
, which joined the UN in 1956, is the second-largest contributor to the UN's regular budget. Its payments had surpassed the sum of those of the United Kingdom, France, China and Russia combined for nearly two decades before 2010. Japan has been one of the largest Official development assistance donor countries. Thus, Japan, along with India, are considered the most likely candidates for two of the new permanent seats. China has stated that it was ready to support India's move for a permanent seat on the UNSC if India did not associate its bid with Japan. This may be contrary to the Indian stand since Japan and India are both members of the G4 and support each other's candidature. Japan has been elected to the Security Council for eleven terms as a non-permanent member.
