Cambodia, Thailand Agree To ASEAN Observers To Monitor Ceasefire

Last month, Cambodia and Thailand witnessed their worst border clashes in over a decade, with artillery fire and airstrikes killing 43 and displacing 300,000.

Top defence officials from Cambodia and Thailand agreed on Thursday to permit ASEAN observers to monitor disputed border areas and help maintain peace after July’s five-day conflict.

The Southeast Asian neighbours saw the in over a decade last month, including exchanges of artillery fire and jet fighter bombing runs that claimed at least 43 lives and displaced more than 300,000 people on both sides of the border.

Fighting continued despite diplomatic interventions from China and Malaysia, the chair of the regional bloc ASEAN, both calling for restraint.

The leaders of Cambodia and Thailand only came to the negotiating table when U.S. President Donald Trump told them that tariff negotiations would not continue unless there was peace, Reuters exclusively reported.

Defence Chiefs Discuss Ceasefire

Cambodian Defence Minister Tea Seiha and Thailand’s acting defence minister Nattaphon Narkphanit met at Malaysia’s Armed Forces headquarters in Kuala Lumpur on Thursday to thrash out the terms of a permanent cessation of hostilities.

“There will be an observation team of ASEAN military attaches based in Thailand and Cambodia, led by Malaysia,” Nattaphon told reporters at a press conference after the meeting, adding that foreign inspectors based in either country would not cross the border.

“Thailand and Cambodia are neighbours with a shared border that can move away from each other … a resolution will allow our people to return to peaceful lives,” he said.

Thailand and Cambodia said in a joint statement that they would hold more talks in two weeks and then again in a month.

The peace conditions were formulated during three days of talks between senior officials in Kuala Lumpur and were finalised on the fourth day in the presence of observers from China and the United States.

“Both sides agreed on the terms of implementation of the ceasefire and improving communication between the two armies,” Cambodian Prime Minister Hun Manet said on social media.

Thailand and Cambodia have quarrelled for decades over undemarcated parts of their 817 km (508 miles) land border, which was first mapped by France in 1907 when the latter was its colony.
