Australia warns of humanitarian crisis as Cambodia–Thailand border war escalates

PHNOM PENH, Cambodia (Dec. 24, 2025) — Australia voiced alarm Wednesday over intensifying military clashes between Cambodia and Thailand, warning of mounting humanitarian consequences and urging both sides to halt hostilities and protect civilians.

In a statement posted on its official Facebook page, the Australian Embassy in Phnom Penh said it was “deeply concerned” about the growing scale and intensity of the conflict, including the use of heavy and destructive weapons.

“We express our condolences to those who have lost family and loved ones, and ask that both sides ensure the protection of civilians, civilian infrastructure and cultural heritage,” the embassy said.

Australia urged Cambodia and Thailand to honor obligations under international law, implement the Kuala Lumpur Joint Declaration as a pathway to de-escalation, and engage in good-faith negotiations at the upcoming General Border Committee meeting. Canberra welcomed mediation efforts by ASEAN, Malaysia and the United States.

The warning comes as Cambodia reports worsening humanitarian conditions. Since Dec. 7, the Ministry of Interior says 21 civilians have been killed, 83 injured and more than 600,000 displaced.

Authorities said homes, schools, hospitals, pagodas, bridges, markets, government buildings and even an ancient temple have been damaged. Cambodia has appealed to global powers and ASEAN partners to intensify diplomatic engagement to stop the war and prevent further civilian suffering.
