ICJ ruled in 2002 on the entire Cameroon-Nigeria land and maritime boundary but the parties formed a Joint Border Commission, which continues to meet regularly to resolve differences bilaterally and have commenced with demarcation in less-contested sections of the boundary, starting in Lake Chad in the north; implementation of the ICJ ruling on the Cameroon-Equatorial Guinea-Nigeria maritime boundary in the Gulf of Guinea is impeded by imprecisely defined coordinates and a sovereignty dispute between Equatorial Guinea and Cameroon over an island at the mouth of the Ntem River; Nigeria initially rejected cession of the Bakassi Peninsula, then agreed, but much of the indigenous population opposes cession; 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
