Senior defence officials from Cambodia and Thailand began talks on Thursday in Malaysia to finalise a settlement to end fighting after a fierce five-day border conflict that ended with an unconditional ceasefire at the end of July.
Last month, Southeast Asia saw its most intense fighting in a decade, including artillery shelling and jet fighter bombing, which killed at least 43 people and forced more than 300,000 to flee their homes on both sides of the border.
The fighting continued despite diplomatic statements by China and Malaysia, which chairs the regional ASEAN bloc, calling for restraint.
The leaders of Cambodia and Thailand only sat down at the negotiating table after US President Donald Trump told them that tariff talks would not continue until peace was achieved.
Cambodian Defence Minister Tea Banh and Thai Acting Defence Minister Nattaphon Narkphanit are due to meet at the Malaysian Armed Forces headquarters in Kuala Lumpur.
The two countries will develop guidelines for resolving border disputes, restoring trust between the armed forces and reaching a ceasefire agreement with measures to minimise tensions and protect civilians, according to a statement by Nattaphon released ahead of the talks.
The terms were formulated during three days of talks between senior officials in Kuala Lumpur and will be finalised on the fourth day in the presence of observers from China and the US.
Thailand and Cambodia have been at odds for decades over unmarked sections of their 817-kilometre land border, which was first mapped by France in 1907 when Cambodia was its colony.
