Cambodia and Thailand's top defence officials agreed on Thursday to allow observers from the ASEAN regional bloc to inspect disputed border areas and help ensure hostilities do not resume following a violent five-day conflict that ended in a ceasefire late in July.

Cambodia and Thailand agreed to uphold a ceasefire, more than one week after a US-backed truce ended the deadliest clashes between the Southeast Asian neighbors in recent history.

Thailand and Cambodia agreed Thursday to extend a shaky ceasefire deal that followed five days of deadly hostilities along their border last month. In the first days of the truce, both Thailand and Cambodia accused each other of breaching the deal with limited skirmishes along their shared 800-kilometre (500-mile) border,

Cambodia and Thailand's top defence officials began a meeting in Malaysia on Thursday to finalise a permanent end to hostilities following a violent five-day border conflict that ended in an unconditional ceasefire late in July.

Thailand and Cambodia have reached a landmark agreement on a 13-point ceasefire plan aimed at de-escalating tensions along their shared border and fostering peace between the two nations.

Interim observer teams from Asean nations will be stationed on both sides of the border, pending the full Malaysia-led mission.

Ceasefire is not merely a pause but a promise to protect lives, Home Minister Datuk Seri Saifuddin Nasution Ismail says.

Thailand and Cambodia have agreed to allow regional bloc ASEAN to act as observers of the ceasefire between the two neighbours, Thailand’s Acting Minister of Defence Nattaphon Narkphanit said on Thursday.

Top defence officials from both countries meet in Malaysia to outline steps for resolving disputes, restoring military trust and protecting civilians.

Malaysia will continue to play its coordinating role in the ceasefire efforts between Thailand and Cambodia, without a need for a full-scale Asean intervention, says Datuk Seri Anwar Ibrahim. The Prime Minister said he had met with both Defence Ministers of Thailand and Cambodia to discuss the details of the protocols that must be observed at the contested borders.
