NewsCambodia denies Thai landmine claims as truce hangs in the balanceCambodia says the mine that wounded four Thai soldiers was a remnant of past conflicts, but Bangkok says the explanation is insufficient.

Cambodia has denied laying new landmines along its border with Thailand after Bangkok suspended the implementation of an enhanced ceasefire signed last month over an explosion that wounded four Thai soldiers.

In a statement on Tuesday, the Cambodian Ministry of National Defence expressed regret at the landmine explosion the previous day in Thailand’s Sisaket province near the countries’ shared border, saying the blast had taken place in an old minefield.

Despite the dispute, “both military forces on the front lines had communicated with each other, and, as of now, the situation remains calm, with no tension having been reported,” the ministry added.

Thailand and Cambodia signed their enhanced truce in Malaysia last month after long-running territorial disputes between the Southeast Asian neighbours led to five days of combat in late July.

The conflict, which killed at least 48 people and temporarily displaced an estimated 300,000, marked their worst fighting in recent history.

The enhanced ceasefire, signed in the presence of United States President Donald Trump, sought to build on an earlier truce brokered in July and included the withdrawal of troops and heavy weapons.

It also called for Bangkok’s release of 18 Cambodian prisoners of war.

The Thai government on Tuesday insisted the Cambodian explanation was insufficient and said it was halting the release of the Cambodian soldiers, which had been slated for Wednesday.

Advertisement Thai Foreign Minister Sihasak Phuangketkeow said his country’s decision would be explained to the US and Malaysia, the chair of the regional bloc, the Association of Southeast Asian Nations, which has facilitated the ceasefire process.

“What they [Cambodia] have said is not sufficient. We have to see what Cambodia’s stance is from now on,” he said.

The Thai military late on Monday said officials had inspected the landmine explosion site in Sisaket and found an explosion pit and three more antipersonnel mines.

Spokesperson Major General Winthai Suvaree said the explosion occurred in an area that Thai soldiers had previously secured. He said that since October 17, the soldiers had removed landmines and laid defensive barbed wire there.

But the wire was destroyed on Sunday, and the soldiers checking the site on Monday stepped on the mine, Winthai said.

“The evidence led to the conclusion that intruders secretly removed the barbed wire and laid the landmines in the Thai territory, targeting the personnel who conduct regular patrols there,” Winthai said, according to the Bangkok Post.

“The act shows Cambodia’s insincerity in reducing conflict and reflects hostility which violates the jointly signed declaration,” he added.

The military said a sergeant lost his right foot in the explosion and the other three suffered minor injuries from shrapnel or the impact of the blast.

There was no immediate comment from the US or Malaysia.

While the Thai-Cambodian truce has generally held since July 29, both countries have traded allegations of ceasefire breaches.

Analysts said a more comprehensive peace pact adjudicating the century-long border dispute at the core of the conflict is needed.
