Libya claims about 25,000 sq km in a currently dormant dispute
in the Tommo region; much of Benin-Niger boundary, including
tripoint with Nigeria, remains undemarcated; only Nigeria and

Joint Border Commission with Cameroon reviewed 2002 ICJ
ruling on the entire boundary and bilaterally resolved differences,
including June 2006 Greentree Agreement that immediately cedes
sovereignty of the Bakassi Peninsula to Cameroon with a phase-out of
Nigerian control within two years while resolving patriation issues;
the ICJ ruled on an equidistance settlement of Cameroon-Equatorial
Guinea-Nigeria maritime boundary in the Gulf of Guinea, but
imprecisely defined coordinates in the ICJ decision and a
sovereignty dispute between Equatorial Guinea and Cameroon over an
island at the mouth of the Ntem River all contribute to the delay in
implementation; only Nigeria and Cameroon have heeded the Lake Chad
Commission's admonition to ratify the delimitation treaty which also
includes the Chad-Niger and Niger-Nigeria boundaries
