Honduras vs. Nicaragua

International Court of Justice (ICJ) ruled on the delimitation of "bolsones" (disputed areas) along the El Salvador-Honduras border in 1992 with final settlement by the parties in 2006 after an Organization of American States survey and a further ICJ ruling in 2003; the 1992 ICJ ruling advised a tripartite resolution to a maritime boundary in the Gulf of Fonseca with consideration of Honduran access to the Pacific; El Salvador continues to claim tiny Conejo Island, not mentioned in the ICJ ruling, off Honduras in the Gulf of Fonseca; Honduras claims the Belizean-administered Sapodilla Cays off the coast of Belize in its constitution, but agreed to a joint ecological park around the cays should Guatemala consent to a maritime corridor in the Caribbean under the OAS-sponsored 2002 Belize-Guatemala Differendum
