He was the Minister of External Relations of Cameroon from 1988 to 1992[1] and the head of United Nations Assistance Mission for Rwanda (UNAMIR).
Working at the Ministry of External Relations, he was Head of the Department of African Affairs, Director for Asia and Africa, Deputy Permanent Representative to the United Nations, and Ambassador to Morocco, Greece and UNESCO.
Booh-Booh's role in Rwanda has been the subject of harsh criticism, primarily by Lieutenant-General Roméo Dallaire and his supporters, contending that he played an instrumental role in forestalling any UN military preventive action against the Rwandan genocide that appeared imminent in the country in mid-1994.
In 1993, Booh-Booh was head of mission of a small force of UNAMIR military personnel (approximately 2,548) that was dispatched by the United Nations to Rwanda, in an effort to aid in the implementation of the Arusha Accords and to keep the peace between Hutu and Tutsi ethnic groups.
He passed this information along to the UN's headquarters in New York and reported his intent to inspect alleged arms caches.
