Under the UN Charter, the Security Council has the primary responsibility for the maintenance of peace and security in the world at large.
China is one of the five permanent members of the 15-nation Council, together with the United States, the United Kingdom, France, and the Russian Federation. The Council has another 10 non-permanent members that are elected in groups of five by the UN General Assembly for two-year terms.
The presidency of the Council rotates among its 15 member states based on the English-language alphabetical order of the countries' names on a monthly basis.
