when did china become a member of the un
China and the United Nations One of the victorious Allies of the Second World War (locally known as the Second Sino-Japanese War), the Republic of China (ROC) joined the UN at its founding in 1945. The subsequent resumption of the Chinese Civil War led to the establishment of the People's Republic of China (PRC) in 1949. Nearly all of mainland China was soon under its control[a] and the ROC fled to the island of Taiwan. The One-China policy advocated by both governments precluded dual representation but, amid the Cold and Korean wars, the United States and its allies opposed the replacement of the ROC at the United Nations, although they were persuaded to pressure the government of the ROC to accept international recognition of Mongolia's independence in 1961. The United Kingdom, France, and other American allies individually shifted their recognitions of China to the PRC and Albania brought annual votes to replace the ROC with the PRC, but these were defeated since—after General Assembly Resolution 1668—a change in recognition required a two-thirds vote.
United Nations The United Nations (UN) is an intergovernmental organization tasked to promote international cooperation and to create and maintain international order. A replacement for the ineffective League of Nations, the organization was established on 24 October 1945 after World War II in order to prevent another such conflict. At its founding, the UN had 51 member states; there are now 193. The headquarters of the UN is in Manhattan, New York City, and is subject to extraterritoriality. Further main offices are situated in Geneva, Nairobi, and Vienna. The organization is financed by assessed and voluntary contributions from its member states. Its objectives include maintaining international peace and security, promoting human rights, fostering social and economic development, protecting the environment, and providing humanitarian aid in cases of famine, natural disaster, and armed conflict. The UN is the largest, most familiar, most internationally represented and most powerful intergovernmental organization in the world.[3]
