Thailand’s military said it had gathered ‘worrisome’ indications that Cambodia has stepped up its military readiness.

Thailand’s military has said it is ready to launch a “high-level operation” to counter violations of its sovereignty, offering its strongest comments yet following the re-eruption of a long-running border dispute with Cambodia.

In a statement on Thursday night, the Thai military said its intelligence had gathered “worrisome” indications that Cambodia has stepped up its military readiness along their shared border.

“The army is now ready for a high-level military operation in case it is necessary to retaliate against the violation of sovereignty,” the statement said.

“Operations of units at the border have been conducted carefully, calmly and based on an understanding of the situation to prevent losses on all sides, but at the same time, are ready to defend the country’s sovereignty to the fullest extent if the situation is called for,” the statement added.
