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.

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 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.
