Cambodian officials responsed to strong rhetoric in the Thai media on Friday, claiming that increased political pressure over the border near Preah Vihear temple could mean an end to a bilateral solution to the problem.
Foreign Affairs Minister Hor Namhong told reporters Friday Cambodia would consider filing a grievance with the UN Secretary General over the border issue if Thai officials did not stop making public claims to a stretch of land along the border.
Thailand and Cambodia are at odds over a 4.6-kilometer stretch of land that each side claims for itself. Cambodian officials maintain that the land, west of Preah Vihear temple, does not belong to Thailand.
Both sides have had troops amassed on the border since July 2008, when Preah Vihear temple was listed as a World Heritage Site under Cambodia.
Cambodia issued a management plan to Unesco's World Heritage committee last week, but Thailand says the plan would eat into Thai soil. Cambodian officials have denied the the claim.
Hor Namhong said Friday he was responding to recent Thai media reports that quoted Thai Prime Minister Abhisit Vejjajiva saying border problems only started after the Unesco World Heritage listing.
