The Special Representative of the Secretary General for West Africa also serves as Chairman of the Cameroon-Nigeria Mixed Commission (CNMC) established in November 2002 by the UN Secretary-General at the request of Presidents Paul Biya and Olusegun Obasanjo of Cameroon and Nigeria respectively. The goal of the Mixed Commission is to facilitate the implementation of the judgment of the International Court of Justice (ICJ) of 10 October 2002.
The mandate covers the following fields:
- Demarcation of the land boundary and delimitation of the maritime boundary between the two countries.
- Withdrawal and transfer of authority in the Lake Chad area, along the land boundary and in the peninsula of Bakassi.
- Demilitarization of the peninsula of Bakassi.
- Protection of the rights of the affected populations.
- Development of projects aiming at promoting the economic joint ventures between Cameroon and Nigeria and cross border cooperation.
- Reactivation of the Lake Chad Basin Commission
Since December 2002, the Mixed Commission has held regular meetings alternatively in Yaoundé and Abuja. To this date, 1947 kilometres of land boundary have been surveyed and agreed by the Parties (the boundary is believed to be 2,100 kilometres long). It managed effectively the process of withdrawal and transfer of authority in Lake Chad area (32 villages involved), along the land boundary and in the Bakassi peninsula. All technicalities pertaining to the delineation of the maritime boundary, including the maritime charts have been settled in compliance with the judgment. Moreover, the Mixed Commission approved the recommendations of the Working Group on the Maritime Boundary, including the provisions for cross-border cooperation on hydrocarbon deposits straddling the maritime boundary (March 2011).
On 15 August 2013, the Security Council issued a press statement about the successful implementation of the Greentree Agreement on the settlement of the dispute over Bakassi (SC/11094) noting the achievement of the Mixed Commission's mediation as an outstanding initiative of preventive diplomacy. This assessment followed an independent report carried out by the European Union which emphasized furthermore the cost-effectiveness of the Mixed Commission’s demarcation process.
Cameroon, Nigeria and the two United Nations country teams, along with partners including the African Development Bank and the European Union, are considering socio-economic projects in the border areas.
