Between summits, the Non-Aligned Movement is run by the secretary-general elected at last summit meeting. As a considerable part of the movement's work is undertaken at the United Nations in New York, the chair country's ambassador to the UN is expected to devote time and effort to matters concerning the Non-Aligned Movement. The Coordinating Bureau, also based at the UN, is the main instrument for directing the work of the movement's task forces, committees and working groups.
