Thailand's military said it is ready to launch a "high-level operation" to counter any violation of its sovereignty, in the strongest words yet in a simmering border dispute with Cambodia that re-erupted with a deadly clash last week.

Thailand’s armed forces are ready to defend the border in the face of a deadly clash with Cambodia that erupted last week, a top official said, adding that the country wants to maintain peace with its neighbor.

Cambodia has firmly reiterated its stance to Thailand, stating it will not withdraw troops from the Mum Bei area as requested by Thailand, citing Cambodian sovereignty.
