The long-simmering border dispute between Thailand and Cambodia has exploded into full-scale clashes. On Thursday, both nations exchanged artillery fire and air strikes, leading to civilian casualties and diplomatic breakdowns. The conflict centers around the Emerald Triangle, a historically contested region that houses several ancient temples along the 817-km-long border.
The current escalation follows landmine injuries to Thai soldiers, the expulsion of diplomats, and an intense blame game between both governments. With F-16 fighter jets deployed, artillery pounding disputed zones, and nine civilians, including a child, reportedly dead, this is one of the worst flare-ups in the region in over a decade.
What Is the Thailand-Cambodia Border Dispute About?
The dispute revolves around control of temple areas and adjacent territory along the Thai-Cambodian border, particularly near the provinces of Surin (Thailand) and Oddar Meanchey (Cambodia).
- The Emerald Triangle, where Thailand, Cambodia, and Laos converge, includes multiple ancient Khmer temples, which both nations claim sovereignty over.
- Disputes date back over a century, intensified by ambiguous colonial-era maps and undemarcated boundaries.
- The conflict first turned bloody in the early 2000s, followed by a weeklong artillery exchange in 2011.
- Tensions reignited in May 2025, after a Cambodian soldier was killed in a border gunfight, plunging the region back into crisis.
Trigger for the July 2025 Escalation: What Sparked the Latest Clash?
- On July 18, a Thai soldier lost a limb to a landmine near the disputed region.
- Thailand accused Cambodia of recently laying landmines, violating past agreements—an accusation Cambodia strongly denied.
- In retaliation, Thailand expelled Cambodia’s ambassador and recalled its envoy.
- Hours later, Cambodia downgraded diplomatic ties, expelling Thai diplomats and recalling most of its own.
- Thursday morning (July 24), Cambodian artillery and rockets hit Thai military and civilian targets, leading to full-blown clashes.
Sequence of Events on Thursday, July 24
- 7:35 am (local time): Thai troops near the Ta Muen temple spot a Cambodian drone overhead. Six armed Cambodian soldiers, one with an RPG, approach the Thai side.
- Thai soldiers shout a warning. At 8:20 am, Cambodian forces open fire near the temple area—just 200 meters from Thai troops.
- Cambodia claims Thailand initiated the conflict by launching “unprovoked” air strikes.
- Thai F-16 fighter jets are deployed. One aircraft bombs a Cambodian military target, escalating the situation dramatically.
- Cambodian officials say two bombs were dropped on a road near a civilian area. They condemn the act as “reckless and brutal military aggression.”
- Thai officials accuse Cambodia of targeting civilians, stating artillery hit a house, killing one person and injuring a five-year-old child.
- A hospital in Thailand’s Surin province was reportedly targeted, according to Bangkok’s foreign ministry.
- Cambodia exercised what it called a “legitimate right to self-defence” under international law.
Diplomatic Fallout and Regional Impact
- Cambodian PM Hun Manet called for an emergency UN Security Council meeting, citing Thai military aggression.
- Thailand shut all border crossings, evacuated civilians, and moved military reinforcements to the area.
- Domestic politics in Thailand were also shaken—Prime Minister Paetongtarn Shinawatra was suspended from office amid an ethics probe.
- A leaked phone call between her and Hun Sen (former Cambodian PM) has sparked further judicial investigations.

Casualties and Humanitarian Crisis
- As of now, nine civilians, including a child, have reportedly died in the crossfire.
- At least three Thai soldiers have been wounded in separate incidents, primarily due to landmines.
- Dozens of families have been displaced, and cross-border trade and transport have been halted.
- Emergency aid efforts are being discussed but are yet to be coordinated on a bilateral or UN level.
What’s Next?
The situation remains volatile:
- Both armies are on high alert, and fresh troop deployments continue.
- Cambodia has announced plans to activate a civilian draft in 2026, indicating deeper militarization.
- ASEAN has yet to issue a formal statement, but international observers are urging restraint.
Historical Context: Why the Temple Areas Matter
Temples like Preah Vihear, Ta Muen Thom, and Ta Krabey lie at the heart of the dispute. In 1962, the International Court of Justice (ICJ) awarded Preah Vihear to Cambodia, but surrounding territory remains hotly contested.
These ruins are not just architectural marvels but are also symbols of national identity, pride, and power projection for both nations.
