The president of the United Nations General Assembly is a position voted by representatives in the United Nations General Assembly (UNGA) on a yearly basis.
The presidency rotates annually between the five geographic groups: African, Asia-Pacific, Eastern European, Latin American and Caribbean, and Western European and other States.
[1] Because of their powerful stature globally, some of the largest, most powerful countries have never held the presidency, including the five permanent members of the United Nations Security Council and Japan.
A few countries had a national elected as president of UNGA twice: Argentina, Chile, Ecuador, Hungary and Nigeria; all the other member states had a national holding this office once (not counting additional special and emergency special sessions of UNGA and also not considering that the then separate West Germany and East Germany held the presidency once each during the Cold War).
In addition to the president, a slate of 21 vice-presidents are elected for each General Assembly session.
