Representatives of the People's Republic of China attend the United Nations, including the United Nations Security Council, for the first time.

China is one of the members of the United Nations and is one of five permanent members of its Security Council. One of the victorious Allies of World War II, the Republic of China (ROC) joined the UN as one of its founding member countries in 1945. The subsequent resumption of the Chinese Civil War between the government of Republic of China and the rebel forces of the Chinese Communist Party, led to the latter's victory on the mainland and the establishment of the People's Republic of China (PRC) in 1949. Nearly all of mainland China was soon under its control and the ROC government retreated to the island of Taiwan.

The United Nations (UN) is the global intergovernmental organization established by the signing of the UN Charter on 26 June 1945 with the articulated mission of maintaining international peace and security, to develop friendly relations among states, to promote international cooperation, and to serve as a centre for harmonizing the actions of states in achieving those goals.

The United Nations Security Council (UNSC) is one of the six principal organs of the United Nations (UN) and is charged with ensuring international peace and security, recommending the admission of new UN members to the General Assembly, and approving any changes to the UN Charter. Its powers as outlined in the United Nations Charter include establishing peacekeeping operations, enacting international sanctions, and authorizing military action. The UNSC is the only UN body with authority to issue resolutions that are binding on member states.
