Nicaragua
territorial disputes with Colombia over the Archipelago de
San Andres y Providencia and Quita Sueno Bank region; the 1992 ICJ
ruling for El Salvador and Honduras advised a tripartite resolution
to establish a maritime boundary in the Gulf of Fonseca, which
considers Honduran access to the Pacific; legal dispute over
navigational rights of San Juan River on border with Costa Rica

Niger
Libya claims about 25,000 sq km in a currently dormant

Chad Commission continues to urge signatories Cameroon, Chad, Niger,
and Nigeria to ratify delimitation treaty over the lake region,
which remains the site of armed clashes among local populations and
militias

Nigeria
ICJ ruled in 2002 on the entire Cameroon-Nigeria land and
maritime boundary but the parties formed a Joint Border Commission
to resolve differences bilaterally and have commenced with
demarcation in less-contested sections of the boundary, starting in
Lake Chad in the north; Nigeria initially rejected cession of the
Bakasi Peninsula; 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, the
unresolved Bakasi allocation, 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; several
villages along the Okpara River are in dispute with Benin; Lake Chad
Commission continues to urge signatories Cameroon, Chad, Niger, and
Nigeria to ratify delimitation treaty over lake region, which
remains the site of armed clashes among local populations and
militias
