There are other intergovernmental organizations that have concluded cooperation agreements with the United Nations. In terms of cooperation structures, some agreements come very close to the relationship agreements concluded under articles 57 and 63 of the UN Charter with the specialized agencies, but due to Charter requirements that the agencies deal with "economic, social, cultural, educational, health, and related fields", organizations with such agreements are not formally specialized agencies of the United Nations.[8][9][10][11][5][6] These organizations are termed Related Organizations by the UN.[14]
