The commander of Thailand's Second Army Region has closed the Chong Sai Taku border crossing with Cambodia in Buri Ram.
Lt Gen Boonsin Padklang gave an order to close the temporary border crossing on Saturday.
Earlier the Chong Sai Taku border crossing had been opened daily to allow border trade, investments and tourism.
The border conflict with Cambodia has been escalating since Cambodian troops entered Thailand’s Chong Bok area in Ubon Ratchathani province in April. The incursion led to the construction of a Cambodian military base where Cambodian soldiers opened fire at the Thai soldiers who approached on May 28.
Then Cambodia brought four disputed areas including Chong Bok to the International Court of Justice.
Thailand later restricted the opening hours of border crossings with Cambodia, apparently to affect the operations of Cambodia's entertainment venues and casinos near the border.
Cambodian Senate President Hun Sen repeatedly demanded the restoration of normal opening hours for the border crossings with Thailand – as heard in a leaked and controversial phone call recording with Thai Prime Minister Paetongtarn Shinawatra.
