    [BANGKOK] Thailand accused Cambodia of planting new land mines on the Thai side of the shared border, in an escalation of a bitter territorial dispute between the two countries.

    Three Thai soldiers were injured when they stepped on a land mine during a routine patrol along an established route within Thai territory on Jul 16, the Ministry of Foreign Affairs said in a statement late on Sunday (Jul 30). The mines were not of a type used by Thailand and were recently laid in a “blatant violation of international law,” it said.

    “The Royal Thai government condemns in the strongest terms the use of anti-personnel mines,” the ministry said, adding that it planned to take action against Cambodia under the United Nations’ Anti-Personnel Mine Ban Convention as a state party while pursuing bilateral channels to resolve the ongoing dispute. “Thailand calls on Cambodia to cooperate on humanitarian demining efforts along the border of the two countries as bilaterally agreed by both Prime Ministers.”

    A spokesperson for the Cambodian government did not immediately respond to a request for comment.

    The border dispute between the two countries has blown up into a major point of contention, especially since a May 28 exchange of gunfire which killed a Cambodian soldier. Thai Prime Minister Paetongtarn Shinawatra subsequently sought to calm tensions in a call with former Cambodian leader Hun Sen, but the conversation was leaked, triggering an uproar at home and the Thai leader’s suspension as premier by a court.

    The foreign ministry’s statement on the mines represents some of its strongest language towards Cambodia since the Constitutional Court suspended Paetongtarn pending an ethics probe into her handling of the dispute.

    The mines were found in Chong Bok, site of the May exchange of fire. Thai officials said that incident occurred because Cambodian soldiers were digging a trench in the border area and opened fire on Thai soldiers, while Cambodia said its troops have long been stationed there and blamed the Thai side for shooting first.

    Both countries have a history of clashes over land disputes but have largely maintained cordial relations since a deadly conflict in 2011 left dozens dead. But since May, both sides have massed troops along the frontier and limited land crossings that act as vital trade links.

    Cambodia has said it wants the International Court of Justice in the Hague to help settle the disputed status of Chong Bok and three other disputed border areas. Thailand does not recognise the court’s jurisdiction. BLOOMBERG
