Tensions along the Cambodia-Thailand border have escalated once again, with Cambodia’s defence ministry accusing Thailand of bombing the bustling Poipet casino hub, a key land crossing between the two nations. The renewed fighting has raised fears of a prolonged conflict, despite claims from US President Donald Trump that a ceasefire had been agreed.

Details of the Poipet Bombing

Cambodia reported that Thai forces dropped two bombs in the municipality of Poipet, located in Banteay Meanchey province, around 11 a.m. local time (04:00 GMT) on Thursday, 18 December 2025. Poipet is a popular destination for Thai gamblers, making it a high-profile target.

The Cambodian interior ministry confirmed that at least four casinos have been damaged by Thai strikes this week. At the time of reporting, Thailand had not officially acknowledged the bombing.

The fighting has resulted in at least 21 deaths in Thailand and 17 in Cambodia, while approximately 800,000 people have been displaced, according to official sources. Thailand also reported that 5,000–6,000 Thai nationals remain stranded in Poipet due to the closure of land border crossings, though air travel remains an alternative.

Truce Denials and Ongoing Hostilities

The conflict is rooted in a longstanding territorial dispute over colonial-era border demarcations and several ancient temple sites along the 800km (500-mile) frontier.

Although President Trump claimed last week that Cambodia and Thailand had agreed to a new ceasefire, Bangkok denied any such agreement. Fighting, which includes artillery, tanks, drones, and jets, has continued daily following a border skirmish earlier this month that reignited hostilities.

Both sides accuse the other of initiating the conflict, claiming self-defense, while civilians remain at risk amid cross-border strikes.

International Mediation Efforts

In a bid to reduce tensions, China announced that its special envoy for Asian affairs would travel to Cambodia and Thailand for a shuttle-diplomacy mission, aimed at bridging gaps and rebuilding peace between the neighboring countries.

Previous attempts at truce, brokered in July by the United States, China, and Malaysia, collapsed within months, highlighting the fragility of peace efforts in the region.

Humanitarian and Economic Impact

The border clashes have disrupted local economies and tourism, with casinos, businesses, and transport infrastructure damaged. Civilians in affected areas face displacement and shortages of essential services. The closure of Poipet’s land border has left thousands stranded, exacerbating the humanitarian impact.

Conclusion

The Cambodia-Thailand border conflict shows no signs of abating, with accusations of bombings, continued fighting, and disputed ceasefires. International mediation efforts, including by China, remain critical to prevent further escalation and civilian casualties.
