A summit meeting (or just summit) is an international meeting of heads of state or government, usually with considerable media exposure, tight security, and a prearranged agenda.
Notable summit meetings include those of Franklin D. Roosevelt, Winston Churchill, and Joseph Stalin during World War II.
[1] During the Cold War, when American presidents joined with Soviet or Chinese counterparts for one-on-one meetings, the media labelled the event as a "summit".
The post–Cold War era has produced an increase in the number of "summit" events.
Nowadays, international summits are the most common expression for global governance.
