UN General Assembly: all 193 Members, one vote each, two-thirds majority on important questions
Background
Established in 1945 under the Charter of the United Nations, the General Assembly is the chief deliberative, policymaking and representative organ of the United Nations.
It comprises all 193 Members of the United Nations and each Member State has one vote.
Votes on designated important issues, such as recommendations on peace and security, the election of Security Council and Economic and Social Council members, and budgetary questions, require a two-thirds majority; other questions are decided by a simple majority.
It approves the United Nations budget, elects the non-permanent members of the Security Council and, on the recommendation of the Security Council, appoints the Secretary-General.
Under its "Uniting for peace" resolution of 3 November 1950, it may recommend collective measures when the Security Council has failed to act owing to the negative vote of a permanent member.
In September 2015 it agreed on a set of 17 Sustainable Development Goals in resolution 70/1.
