Cambodia on Monday has said it would stop importing Thai fruits and vegetables if Thailand refused to lift border restrictions imposed following a deadly clash in one of the disputed areas between the two countries.

Cambodia's influential former leader Hun Sen on Monday (Jun 16) issued an ultimatum to Thailand to lift border crossing restrictions or his country will ban all Thai fruit and vegetable imports in the latest round of the border spat between the two countries.

Cambodia said on Sunday it has asked the International Court of Justice to resolve its border disputes with Thailand, after a flare-up in the long-running row led the Southeast Asian neighbours to mobilise troops on both sides of the border.
