Thailand and Cambodia have agreed to establish interim observer teams to monitor a fragile ceasefire that ended five days of deadly border clashes.

Top defence officials of Thailand and Cambodia began talks in Malaysia on Monday to hold the ceasefire on the border, a week after the worst fighting broke out between the two Southeast Asian countries in decades.

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.
