PHNOM PENH/BANGKOK - Cambodian Prime Minister Hun Manet said on Sunday that two more border crossings with Thailand were completely shut down amid an ongoing border dispute between the two ASEAN member states.

Hun Manet said the Thai army Saturday night informed the governor of Cambodia's Oddar Meanchey province about its unilateral decision to close Choub Korki border checkpoint from Sunday onwards.

"I agreed with the governor's response that we will also close that border checkpoint permanently," Hun Manet said in a post on his official social media platforms.

"I also ordered the governor to inform the Thai side that Cambodia has also decided to close another checkpoint at Choam, altogether with Choub Korki checkpoint from today onwards," he added.

The Cambodian prime minister said that since June 7, the Thai army has unilaterally implemented closures of border checkpoints between Cambodia and Thailand without much consideration of its negative effects on the people of both countries.

"It has never been Cambodia's intention to cause difficulty for people in our both countries who need to use border checkpoints. Yet, if the Thai army continues to use this method to put pressure on Cambodia, Cambodia can answer accordingly at any time," Hun Manet said.

The Thai army has announced the closure of the trade point at Chong Sai Taku in Buriram province, effective from Saturday.

In a statement on Sunday, the Thai army said that it has implemented control measures for opening and closing all types of crossing points along the Thai-Cambodian border to comply with the security situation.

Thai media reported on Sunday that the Thai army prepared to close two more crossing points in response to the Cambodian side's announcement to close two border crossings.

Thailand's Ministry of Foreign Affairs on Sunday issued a public advisory urging Thai citizens to avoid non-essential travel to Cambodia due to heightened tensions between the two neighboring countries.
