GUATEMALA CITY (AP) - Guatemalans have moved a step closer to resolving a longstanding territorial dispute with neighboring Belize, voting to send the issue to the International Court of Justice. However, Belize has yet to hold its own referendum as stipulated under a 2008 agreement with Guatemala, under which both countries would ask the court to take up the matter. Guatemalans will receive a ballot with the question:

"Do you agree that any legal reclaim taken by Guatemala against Belize over continental and island territories and any maritime areas corresponding to said territories be submitted to the International Court of Justice for definitive resolution and that it also determine the borders of the respective territories and the area of each part?" Guatemala recognized Belize's independence in 1991 without dropping its territorial claim. (AP Photo/Moises Castillo)

Guatemala claims some 4,200 square miles (11,000 square kilometers) of terrain administered by Belize - essentially the country's entire southern half. While Guatemala gained its independence from Spain in 1821, Belize became the British Crown colony of British Honduras in 1862, renaming itself Belize in 1973 and earning its independence in 1973.

Millions of Guatemalans are summoned to participate in a referendum in which they will determine if they submit to the International Court of Justice the territorial, insular and maritime dispute with Belize.
