ASEAN members are holding talks on a request from Cambodia for help in resolving a deadly border dispute with Thailand. Ministry of Foreign Affairs spokeswoman Nguyen Phuong Nga said in a statement that as ASEAN chair, Vietnam is actively consulting other ASEAN countries about the proposal that ASEAN mediates over the Preah Vihear dispute. Cambodia's foreign minister Hor Namhong on Saturday appealed to the 10-member Association of Southeast Asian Nations for help, in order to avoid any large scale armed conflict. He said a stalemate with Thailand had extinguished any hope of further bilateral negotiations. The neighbouring nations have been locked in a troop standoff at their border since July 2008, when the ancient Preah Vihear temple was granted UNESCO World Heritage status. ASEAN secretary general Surin Pitsuwan said on Monday he would await a decision by the bloc's foreign ministers before responding to Cambodia's request for regional help. The World Court ruled in 1962 that the temple belonged to Cambodia, although it’s main entrance lies in Thailand. The Thai-Cambodia border has never been fully demarcated, partly because it is littered with landmines left over from decades of war in Cambodia.
