Thailand-Cambodia Border War Reignites: Airstrikes Resume as Ceasefire Collapses, Civilians Flee
Thailand launched airstrikes on Cambodia on Monday, shattering a fragile ceasefire and reigniting a border dispute that had been dormant since the summer. Fighter jets streaked across the disputed border; shells rained down on temples; 35,000 Thai civilians were evacuated Sunday and Monday as the air and ground attacks killed four Cambodian civilians and one Thai soldier. Both sides traded accusations—Thailand claimed self-defense against Cambodian troop aggression; Cambodia countered that Thai F-16s indiscriminately targeted temples and civilian areas. A journalist was hit by shrapnel; villages burned. All this unfolded after Thailand suspended a Trump-backed peace agreement last month following a landmine explosion, exposing the fragile diplomacy that had masked deep-seated territorial disputes rooted in century-old colonial-era border mapping.
This fighting marks the second major clash in five months. The open warfare in July—involving fighter jets, missiles, and ground troops—killed 43 people and displaced 300,000. The US, China, and Malaysia brokered a ceasefire. A declaration co-signed by Trump in October promised trade agreements; the suspension in November scuttled them. Sporadic skirmishes preceded Monday’s escalation—evidence of the simmering tensions beneath the nominal agreements. For border communities like that of Pannarat Woratham, a 59-year-old Thai farmer, the trauma is being repeated: evacuated in July, evacuated again. “This shouldn’t be happening again,” she lamented to AFP, sheltering in a temple with thousands of others.
Historical Context: Colonial Borders, Eternal Disputes
This conflict is a century old: French colonial administrators drew borders that overlapped. After independence, disputes arose over Thai-Cambodian maps; International Court of Justice (ICJ) rulings (1962, 2013) awarded the disputed temples—Preah Vihear, Ta Moan—to Cambodia, yet both countries continue to claim each other’s territory. Preah Vihear sits atop disputed plateaus; monks guard the ancient stones while soldiers surround the temples. Ta Moan Thom, Ta Krabey—centuries-old sacred sites—have become battlegrounds.
The root cause: colonial ambiguities were never clearly resolved. Modern nations refuse to compromise; nationalist pride transforms borders into symbols of sovereignty. Every clash reopens old, unhealed wounds.
Monday’s Escalation: Accusations and Fog of War
Thai army spokesman Winthai Suwaree presented Thailand’s version of events: Cambodian forces attacked; Thailand responded in self-defense. One Thai soldier was killed, eight were wounded. Airstrikes targeted “military positions along the line of confrontation,” with “no impact on civilians.” F-16 aircraft destroyed military infrastructure, “limiting damage,” and silenced supporting fire.
Cambodian Defense Ministry spokeswoman Mali Sochhiata flatly contradicted this: Thai forces attacked first, targeting Cambodian troops in Preah Vihear and Oddar Meanchey provinces around 9:00 a.m. Monday. Thai tanks fired on the Ta Moan Thom temple; F-16 missiles struck civilian areas; houses burned; civilians fled; a journalist was hit by shrapnel. Cambodia did not retaliate—the victim’s narrative. Civilian deaths contradicted Thai claims of precision targeting.
Independent verification is scarce—both sides control the flow of information. Journalists are threatened; access is restricted. The stories diverge; the truth is shrouded in the fog of war.
Civilian Toll and Displacement Crisis
Four Cambodian civilians confirmed dead; journalist injured. Thai airstrikes destroyed homes, farms, and livelihoods. In Oddar Meanchey province, Met Measpheakdey reported shelling around the sacred temples of Ta Moan Thom and Ta Krabei, simultaneously destroying spiritual centers and places of refuge.
Thai side: 35,000 people evacuated from Surin, Buriram, and other border provinces on Sunday and Monday. People sought refuge in temples; schools were closed; evacuation routes were jammed. The trauma is recurring—the same people are fleeing along the same routes for the second time in five months. Psychological impact: displaced people are living in fear; economies have collapsed; agricultural seasons have been disrupted.
Cambodia reported the evacuation of 1,157 families from Oddar Meanchey. Total displacement: potentially more than 50,000, possibly reaching the 300,000 figure seen in July if the fighting escalates.
The Collapsed Trump-Backed Deal: Why October’s Peace Failed
October 2025: Trump signed a joint declaration promoting “new trade agreements,” contingent on extending the ceasefire. It was presented as a victory – Trump as peacemaker and dealmaker. Markets soared; optimism was at its peak. Yet the November collapse was swift and brutal. Thailand cited a landmine explosion that injured soldiers; it suspended participation. Allegations of Cambodian violations; disputes over demilitarization deadlines; mutual recriminations.
Trump’s “peace” lacked substance: no enforcement mechanism, no international observers, no accountability clause. Trump’s characteristic dealmaking – transactional, superficial, personality-driven. Without an institutional framework, the ceasefire crumbled.
Now, the Trump administration is silent – no statements, no diplomatic pressure (unlike the flurry of activity in 2024). The president’s focus is on China in the Indo-Pacific; Southeast Asia is a secondary concern. Washington has largely ignored the Thai-Cambodian spat.
Regional Mediation Crumbles: ASEAN’s Futility
Malaysian PM Anwar Ibrahim urged halt Monday: “Our region cannot afford cycles of confrontation.” Chair of ASEAN, Malaysia brokered July ceasefire via U.S., China backing. Yet ASEAN’s consensus-driven model struggles coercive crises—no enforcement authority, no binding decisions. Thailand-Cambodia neither comply nor face consequence.
ASEAN’s weakness exposed: fundamental disputes transcend diplomatic platitudes. When land, temples, national honor crystallize, lawyers’ words evaporate.
Military Dynamics: Asymmetric Capabilities
Thailand commands air superiority: F-16 fleet, helicopters, missiles. Cambodia lacks fighter jets; relies ground troops, BM-21 rockets. Asymmetry should favor Thailand, yet Cambodian terrain—temple plateaus, dense jungle—negates technological edge. Ground combat favors entrenched defenders.
Thai airstrikes precise yet civilians inevitably caught—temple proximity, civilian-military overlap, collateral damage unavoidable. Precision claims tested; civilian deaths suggest otherwise.
Broader Southeast Asia Tensions: China-U.S. Proxy Friction
Lurking backdrop: Cambodia leans Beijing; Thailand courts U.S./Japan balancing. Border disputes become geopolitical proxy battlegrounds. Chinese economic influence over Cambodia; U.S. military ties with Thailand. Flashpoint risks escalation beyond bilateral—ASEAN fracture, great power confrontation.
Preah Vihear becomes symbol: spiritual sanctuary politicized by superpowers. Neither Washington nor Beijing wants direct confrontation, yet proxy dynamics simmer.
Economic Costs and Regional Stability
Thailand’s tourism economy bleeds from border instability. Surin province—border gateway—evacuations kill tourism, agriculture. Repeat crises deter investment; development stalls. Cambodia faces capital outflows; Cambodia tourism (Siem Reap proximity) threatened.
Bilateral trade ($5B annually) risks disruption. Manufacturing supply chains vulnerable. Regional contagion: Vietnam eyes opportunities; Myanmar exploits distraction.
Escalation or De-escalation?
Short term: Likely to continue through Monday-Tuesday as both sides attempt to find a solution. Then a potential stalemate—neither side is militarily dominant; costs are mounting.
Medium term: International mediation has resumed (US, China, ASEAN) but there is room for skepticism—Trump is distracted, Beijing is calculating. Structural disputes remain unresolved; a tactical ceasefire is the best possible outcome.
Long term: Enforcement by the International Court of Justice is weak; borders have been disputed for generations. Unless Thailand and Cambodia reach a bilateral agreement (unlikely given the nationalism involved), the cycle of conflict will continue.
