Why did the United Nations recognize the Comorian archipelago as one nation after independence?

The United Nations recognized the Comorian archipelago as one nation following its independence in 1975 because it affirmed the territorial integrity of the entire archipelago as a single entity.1

While the French National Assembly had held that each individual island should decide its own status—leading the majority of inhabitants on Mayotte to favor continued French rule—Comorian President Ahmed Abdallah declared the entire archipelago independent on July 6, 1975. Despite France’s subsequent decision to administer Mayotte separately and maintain its control, the United Nations passed a resolution in 1979 explicitly affirming the sovereignty of Comoros over Mayotte. This stance, which has also been supported by the African Union, reflects the international recognition of the archipelago's historical and political unity as a single nation-state.123
