In consonance with the 2006 Enabling Act Establishing the Commission, the Department is responsible for negotiation, demarcation, delimitation, management of our international boundaries and holding of trans-border cooperation workshops with all our neighbours (both land and maritime).  Nigeria shares boundaries with Niger, Chad, Cameroon, Benin, Ghana, Sao Tome and Principe as well as Equatorial Guinea.

The demarcation exercise between Nigeria and Chad Republic had been completed; while demarcation exercises are on going between Nigeria-Cameroon, Nigeria-Niger and Nigeria-Benin. Fresh efforts are initiated to extend the Nigeria-Equatorial Guinea maritime boundary beyond the present point G.  The Department is further involved in managing the issues of straddling settlements, re-establishment of pillars, Vista Clearance and resettlement of population affected by the demarcation exercises.


Nigeria convinced Benin Republic not to accept the 1981 report of the Joint Team of Experts and adopted the method of equidistance which is more favourable to Nigeria.

Nigeria and Benin agreed to a maritime boundary on 18th February, 2005.

Signed Treaty on the Maritime Boundary and Memorandum of Understanding (MOU) in Abuja on 4th August, 2006.
