Thailand and Cambodia have agreed to an unconditional ceasefire following intervention by United States President Donald Trump, bringing an end to the five-day conflict between the two Asian countries.

“This is a vital first step towards a de-escalation and the restoration of peace and security,” Malaysian Prime Minister Anwar Ibrahim, who mediated the negotiation in Kuala Lumpur, said in a press release, noting that the ceasefire would take effect at first light on July 29.

More than 35 people have been killed and thousands more displaced after violence broke out between Thailand and Cambodia last week over a long-disputed border area, which is home to a smattering of ancient temples.

Both countries exchanged heavy artillery and rockets, with Thailand even launching air strikes on Cambodian military positions, marking the deadliest escalation since violence raged from 2008 to 2011 over the territory.

Meanwhile, Cambodian Prime Minister Hun Manet called the talks a “very good meeting,” adding that he hoped the two countries would cease hostilities immediately.

He also thanked Messrs Trump and Ibrahim for their contribution in striking the deal.

Commenting on the development, Thailand’s acting Prime Minister, Phumtham Wechayachai, simply told reporters at the Bangkok airport that Thailand negotiated a pause in fighting “in good faith”.
