The Greentree Agreement was the formal treaty which resolved the Cameroon-Nigeria border dispute over the oil and natural gas rich Bakassi peninsula. The dispute had roots as far back as 1913, 1981, 1994, and 1996 armed clashes between Nigeria and Cameroon took place in Bakassi. The dispute was referred to the International Court of Justice and on 10 October 2002 the ICJ ruled in favor of Cameroon. 
On 12 June 2006, Nigerian President Olusegun Obasanjo and Cameroonian President Paul Biya, signed the Greentree Agreement concerning the withdrawal of troops and transfer of authority in the Peninsula. The withdrawal of Nigerian troops was set for 60 days but allowed for a possible 30-day extension while Nigeria was allowed to keep its civil administration and police in Bakassi for another two years.
A follow-up committee, composed of representatives from Cameroon, Nigeria, the UN, Germany, the USA, France and the UK, was created to monitor the implementation of the agreement.
