evidence: Honduras has also staked a claim to a portion of Belize’s territory – in its case the Sapodilla Cayes, which had been enshrined in its constitution as part of its national territory in 1982. In a paper titled, The Sapodilla Cayes: Geopolitical Asterisk in the Bay of Honduras by Tim Hudson, of the Department of Geography, University of Southern Mississippi, and J. Millard Burr, Special Assistant to the Geographer in the US Department of State, it is noted that the proposal, under the Heads of Agreement of 1981, to allow Guatemala "use and enjoyment" of these cayes, led to the resurrection of the Honduran claim. "Modern Honduran ‘irredentists’ contend that the Sapodillas [Zapotillos] are part of the Bay Island ‘archipelago,’" the authors say, noting, however, that the language of the 1859 treaty with Guatemala "implied that Guatemala considered the Sapodilla Cays, although not mentioned by name, as part and parcel of the ‘British Honduras.’" [...] The CIA Factbook on international disputes says that 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.
