New Mines and Skirmishes Threaten Travel, Trade on Thai-Cambodia Border

Anxious calm has returned to the forested ridges between Sa Kaeo, Si Sa Ket and Cambodia’s Oddar Meanchey, yet competing statements from Bangkok and Phnom Penh show that the November skirmishes are far from settled. Thai officials insist that Cambodian troops triggered the latest clash and quietly laid new antipersonnel mines, while Cambodia portrays the incidents as Thai aggression and relics of past wars. The disagreement now threatens a fragile cease-fire, regional trade routes and the seasonal flow of tourists heading to the northern edge of Angkor.

Standoff Rekindles Familiar Border Tensions

For residents of Khun Han, Kantharalak and Aranyaprathet, sporadic gunfire is an unwelcome reminder of 2008-2011, when ownership of ancient temples ignited gun battles. The current dispute began on 10 November, according to the Royal Thai Army, when a Thai patrol lost a soldier to a freshly buried PMN-2 mine inside Thai territory. Two days later Cambodian troops allegedly opened fire toward a Thai observation bunker near Ban Nong Ya Kaeo, prompting Thai soldiers to release what the army describes as warning shots. Phnom Penh’s foreign ministry counters that Thai forces fired first and hit civilians, a claim Thai officers dismiss as impossible because the zone is “dense jungle with no households.”

Exchange of Fire on 12 November

Thai forensic teams escorted the ASEAN Observers Team (AOT) to the contested slope where they documented bullet scars on sandbagged bunkers facing Cambodia. Maj-Gen Winthai Suvari, the army spokesman, says those marks prove the initial volley came from the east. He adds that Thai troops adhered to strict rules of engagement, firing only into the tree line and ceasing once the opposite side fell silent. Cambodia disputes the narrative, saying its border guards neither provoked nor returned fire and demanding that Bangkok publish raw video from Thai helmet cameras. Both countries released separate photo sets, but third-party verification remains incomplete.

Fresh Landmines or Legacy Threats?

Landmines, long a scourge in this corner of Southeast Asia, have become the sharpest political weapon in the current row. Thailand argues that the PMN-2 devices recovered on 10 November feature manufacturing codes inconsistent with stocks cleared during previous joint demining. Cambodian officials reply that decades-old munitions often resurface after monsoon floods. The disagreement has practical consequences: Thailand has suspended implementation of a joint border declaration signed in Kuala Lumpur in July, freezing coordinated clearance work until “all violations cease.” International demining agencies worry the pause will slow efforts to turn the border into a mine-free economic corridor by 2030.

Competing Narratives, Competing Diplomacies

Beyond the physical front line, a war of communiqués is unfolding. Bangkok’s foreign ministry briefed diplomats, the UN Mine Action Service and donor missions, accusing Cambodia of breaching the Ottawa Treaty. Phnom Penh fired back, saying Thailand leaked incomplete findings that “undermine trust.” Cambodia has also alleged severe human-rights abuses, including the gang rape of an 18-year-old villager on 15 November—charges the Thai government brands “fake news.” The tit-for-tat has already derailed small-scale prisoner exchanges and forced both armies to keep artillery batteries on alert.

Why the Dispute Matters Beyond the Frontline

A new spasm of violence would reverberate far beyond the immediate vicinity of Preah Vihear, Ta Muen Thom and the dusty markets along Highway 33. Exporters fear that checkpoints could close just as year-end fruit shipments increase. The earlier halt in U.S. tariff talks with Thailand illustrates how border flare-ups can complicate broader diplomacy. Tourism operators in Siem Reap and Buriram have started fielding cancellation calls from cautious travelers, while Chinese embassies are pressing for stronger safety guarantees after a Chinese national stepped on a mine on 29 November. The situation also tests ASEAN’s credibility: the bloc helped broker July’s cease-fire, yet to date has issued only muted reminders for “maximum restraint.”

What Comes Next

Thai commanders say they will stick to a defensive posture but reserve the right to respond decisively if fired upon again. Cambodia demands an independent inquiry and the return of its detained soldiers. With rice-harvest season ending, the dry months ahead traditionally allow easier troop movements, raising the stakes. Diplomats in Bangkok expect quiet shuttle missions by Malaysia, which chaired the July peace deal, while the AOT prepares another fact-finding trip that both sides claim will vindicate them. For border communities and traders, the hope is simple: that political leaders, not infantry units, dictate what happens on the frontier during the crucial weeks leading into the New Year holidays.
