Recently, China has taken over as president of the UN Security Council for the month of March 2020.
The Security Council was established by the UN Charter in 1945. It is one of the six principal organs of the United Nations.
The other 5 organs of the United Nations are—the General Assembly, the Trusteeship Council, the Economic and Social Council, the International Court of Justice, and the Secretariat.
Its primary responsibility is to work to maintain international peace and security.
The council has 15 members: the five permanent members and 10 non-permanent members elected for two-year terms.
The five permanent members are the United States, the Russian Federation, France, China and the United Kingdom.
Each member of the Security Council has one vote. Decisions of the Security Council on matters are made by an affirmative vote of nine members including the concurring votes of the permanent members. A "No" vote from one of the five permanent members blocks the passage of the resolution.
Any member of the United Nations which is not a member of the Security Council may participate, without vote, in the discussion of any question brought before the Security Council whenever the latter considers that the interests of that member are specially affected.
The council's presidency is a capacity that rotates every month among its 15 members.
