The clashes reflect heightened political and social tensions in both countries, fuelled by slowing economies that will be further hit by the Trump administration’s tariffs.

Vietnam is concerned about the current escalation of tensions in the border area between Cambodia and Thailand, spokesperson of the Ministry of Foreign Affairs Pham Thu Hang said on July 24.

The conflict between Thailand and Cambodia has resulted in casualties and raised concerns of a prolonged crisis.

Of the six F-16 fighter jets that Thailand readied to deploy along the disputed border, one of the aircraft fired into Cambodia and destroyed a military target, the Thai army said.

Caught between the United States and China, Vietnam and Cambodia choose economic pragmatism over political frictions.

The government of Thailand declared martial law in eight provinces along its border with Cambodia on Friday evening.

More than 140 Vietnamese nationals were arrested in Cambodia; consular support and identity checks are underway.

An 83rd-minute winner saw Vietnam claim a 2-1 win over Cambodia to finish top of Group B and advance into the ASEAN U-23 Championship semifinals.

This is the moment a Multiple Launch Rocket System fired missiles from Cambodia into Thailand as 15 civilians were killed in border clashes. Footage shows the military weapon in Preah Vihear province launching a fusillade of rockets toward Thailand's Surin province on July 24.
