Cooperation between the United Nations and regional organizations is based on Chapter VIII of the United Nations Charter
. Regional efforts complement international initiatives and action through the United Nations. Regional organizations are important partners of the United Nations, as each organization has its particular role and expertise. The Secretary-General has therefore encouraged closer and more effective cooperation between the United Nations and regional organizations.
Facilitating cooperation with regional organizations is part of the mandate of the United Nations Office at Geneva, and reinforcing relations with regional arrangements remains one of the priorities of the Office. In this spirit, the Director-General regularly meets representatives of regional organizations and participates in conferences and events organized by them.
