Thailand has suspended the implementation of a United States-brokered peace agreement with neighbouring Cambodia after a landmine blast near their border injured two of its soldiers.

Thai Prime Minister Anutin Charnvirakul said after yesterday’s incident that all action set to be carried out under the truce will be halted until Thailand’s demands, which remain unspecified, are met.

There was no immediate response from the Cambodian government. Thai Defence Minister Natthaphon Narkphanit said the army is still investigating whether the mine was newly laid.

Thailand has previously accused Cambodia of laying new mines in violation of the truce, a charge that the Cambodian government denies.

Thailand and Cambodia signed a ceasefire on the sidelines of the Association of Southeast Asian Nations (ASEAN) summit in Malaysia last month after territorial disputes between the two Southeast Asian countries led to five days of border clashes in July.

Under the terms of the ceasefire, Thailand should release 18 Cambodian soldiers, and both sides must begin removing heavy weapons and land mines from the border.
