Ten Thai soldiers were wounded in the latest border clash in Surin province, early on Tuesday morning.
As Bangkok Post reported, the fighting occurred when Cambodian soldiers tried to capture Ta Kwai and Ta Muen Thom temple ruins.
Col Prawit Hookaew said the 2nd Army has sufficient military strength to cope with the situation without having to call for reinforcements.
"I can assure you that we can protect our sovereignty with our border defence forces", he said.
The latest incident brought the number of wounded up to 42 on the Thai side since the fighting began on Friday, while the death toll remained at five.
