Bangkok: Thailand has announced that it will suspend the implementation of its recently signed peace deal with Cambodia, citing new tensions over a landmine explosion along their shared border. The decision comes just weeks after both countries agreed to a ceasefire aimed at ending months of deadly clashes.

Government spokesman Chai Wattanachai said Bangkok will temporarily halt all steps related to the “Kuala Lumpur Peace Accord” and will inform Washington, which had supported the deal signed in October in the presence of U.S. President Donald Trump.

The Thai government accuses Cambodia of laying new landmines in the Sisaket border area, where two Thai soldiers were reportedly injured over the weekend. Officials said the discovery violated the peace agreement’s commitment to de-mine the border zone.

Cambodia strongly rejected the accusation, saying no new mines had been planted and urging Thailand to avoid patrols in old minefield areas that remain dangerous from past conflicts. Phnom Penh reaffirmed its commitment to the October deal and said it was ready to work through established border committees to resolve the issue.

The peace accord, signed during the ASEAN summit in Kuala Lumpur, called for the withdrawal of heavy weapons, joint monitoring along the border, and coordinated de-mining operations. The agreement was seen as a major step toward restoring calm after violent clashes earlier this year that killed at least 36 people and displaced nearly 200,000 residents on both sides.

Analysts say the suspension of the deal could strain the fragile peace between the two Southeast Asian neighbors. “Trust is very fragile at this point,” said a regional security expert in Bangkok. “If either side feels the other is violating the agreement, it could easily spiral back into confrontation.”

Thailand described its move as a temporary pause, saying it expects Cambodia to address its concerns before the peace process continues. The United States and Malaysia, which helped broker the original accord, have not yet issued official statements on the latest development.

Observers believe the situation may test ASEAN’s role as a regional mediator and could influence broader security efforts in Southeast Asia, where tensions over borders and migration remain sensitive. For now, both governments insist they want to avoid renewed fighting, but the suspension adds uncertainty to the already fragile truce.
