A Cambodian government official has sung praise to U.S. President Donald Trump for "bringing about peace" after Thailand and Cambodia agreed to a cease-fire starting at midnight local time on Monday.

The leaders of Cambodia and Thailand agreed to a ceasefire in a bid to bring an end to their deadliest conflict in more than a decade.

The Thailand-Cambodia border, where fighting has raged since last week, is now calm following a ceasefire deal and military commanders from both sides are set to meet for talks on Tuesday, acting Thai Prime Minister Phumtham Wechayachai said.

The two sides held peace talks in Malaysia after US President Trump suggested he would not resume trade talks if hostilities continued.

Thailand has accused Cambodia of violating a ceasefire agreement reached on Monday after days of deadly clashes along their disputed border, but negotiations between the two sides will continue.

Negotiations are ongoing between the militaries of Thailand and Cambodia on Tuesday, a Thai army spokesman said, even as the Thai side accused Cambodian troops of multiple attacks in violation of a ceasefire that came into effect at midnight.

Thailand has accused Cambodia of "deliberately" violating a ceasefire the two countries had agreed on Monday to end border clashes that have killed at least 33 people and displaced thousands. It's a shaky start for the ceasefire, which was meant to bring an end to five days of bombardment and rocket attacks along their shared border.

Thailand and Cambodia are disputing whether their ceasefire is holding, the morning after they agreed to stop fighting in a deal reached in Malaysia under U.S. pressure.

Following border conflict that killed dozens of people, Thailand and Cambodia agreed to an "immediate and unconditional ceasefire" on Monday.

U.S.-backed talks to end the border war, in which militaries have killed dozens of people and displaced hundreds of thousands, began on Monday in Malaysia.

The fighting, which began last Thursday after a land mine explosion injured Thai soldiers, has killed at least 35 people and displaced over 260,000 people.
