Thailand and Cambodia reinforcing troops on disputed border after May skirmish, Thai minister says

BANGKOK: Thailand has reinforced its military presence along a disputed border with Cambodia, following an increase in troops on the other side, Thailand’s defence minister said on Saturday (Jun 7), as tensions simmer following a deadly clash.

For days, the two Southeast Asian governments have exchanged carefully worded statements committing to dialogue after a brief skirmish in an undemarcated border area on May 28 in which a Cambodian soldier was killed.

But Phumtham Wechayachai, who also serves as Thailand’s deputy prime minister, said that during talks bilateral talks held on Thursday, Cambodia had rejected proposals that could have led to a de-escalation.

“Furthermore, there has been a reinforcement of military presence, which has exacerbated tensions along the border,” Phumtham said in a statement.

“Consequently, the Royal Thai Government has deemed it necessary to implement additional measures and to reinforce our military posture accordingly.”

He did not provide details on the extent of reinforcements by either side.

In a separate statement on Saturday, the Thai army said Cambodian soldiers and civilians had repeatedly made incursions into Thailand’s territory.

“These provocations, and the build up of military forces, indicate a clear intent to use force,” the Thai army said, adding that it would take control of all Thai checkpoints along the border with Cambodia.

A spokesperson for Cambodia’s foreign ministry did not immediately respond to questions from Reuters.

The military reinforcements come despite efforts by Malaysian Prime Minister Anwar Ibrahim, who is the current chair of the Association of Southeast Asian Nations, and China to reduce tensions.

Thailand and Cambodia have for more than a century contested sovereignty at various undemarcated points along their 817km land border, which was first mapped by France in 1907 when Cambodia was its colony.

Tension escalated in 2008 over an 11th-century Hindu temple, leading to skirmishes over several years and at least a dozen deaths, including during a weeklong exchange of artillery in 2011.

Current governments in both countries, however, have enjoyed warm ties. Former leaders Thaksin Shinawatra of Thailand and Cambodia’s Hun Sen have had a close relationship, and Thaksin’s daughter and Hun Sen’s son are now the incumbent prime ministers of their countries.

Still, nationalist sentiment has risen in Thailand and the Thai military said on Friday that it is ready to launch a “high-level operation” to counter any violation of its sovereignty.

Cambodia said this week it would refer disputes over four parts of the border to the International Court of Justice and asked Thailand to cooperate.

Phumtham reiterated in his Saturday statement that Thailand does not recognise the jurisdiction of the court and proposed that all boundary-related issues be resolved through bilateral negotiations. 

The two countries are due to meet for talks on Jun 14.
