Thai soldiers have been put on full alert along the disputed border with Cambodia and been warned that an armed clash is possible, Second Army Region commander Viboonsak Neepal said on Thursday.
Lt-Gen Viboonsak said the Cambodian army had begun deploying more troops and artillery, including 10 large cannons and six tanks, near Preah Vihear temple.
The new Cambodian troops were dressed in new uniforms and armed with new rifles. They had set up camp about two kilometres across the border from Chong Sa Ngam in Si Sa Ket.
Thai troops stationed along the border now had units on alert around the clock, he said.
"If there are bullets coming from the other side, the Thai army is ready to retaliate by any means necessary.
"I have ordered all troops to show patience but be alert, and reminded them not to underestimate the situation," he said.
Meanwhile, Cambodian villagers continued to buy goods at the Thai market as usual.
Defence Ministry spokesman Chittisak Charoensombat said both
countries had dispatched their troops to the border, but they had no intention to clash.
He said each country only wanted to protect its own soveriegnty.
"The Thai army is capable and ready for battle, but we will not invade
or be the first to start using force," Maj-Gen Chittisak said.
Defence Minister Prawit Wongsuwon will make an official visit to Cambodia
on Saturday to discuss the border dispute, he said.
