US-Brokered 72-Hour Ceasefire Holds on Thai-Cambodian Border; Trade Down ฿500M
Fewer rockets were fired overnight along the Thai-Cambodian frontier, but the hard work of turning a fragile หยุดยิง into genuine peace is only beginning. Washington has offered to keep the two neighbours talking; Bangkok businesses are counting every lost baht; and border families are watching the clock on a 72-hour test period that will decide whether soldiers go home—or reload.
Key things Thai readers should keep an eye on
• Ceasefire took effect at 12:00 Saturday and will be reassessed after 72 hours.
• United States says it is ready to mediate if Phnom Penh and Bangkok hit an impasse.
• Trade across the frontier has already shrunk 36.7 % this year, costing up to ฿500 million per day.
• ASEAN observers are deploying within 24 hours to monitor troop positions and airspace violations.
• A decision on releasing 18 Cambodian prisoners of war rests on whether guns stay silent through Tuesday.
Washington’s new tone—and why it matters in Bangkok
The phone line between the US State Department and Cambodian Prime Minister Hun Manet crackled into life just hours before Saturday’s cease-fire was announced. Secretary of State Marco Rubio repeated President Donald Trump’s view that a prolonged conflict “helps no one” and offered to “facilitate the next round of dialogue”. For Thai officials, the message was a reminder that foreign pressure can shift battlefield calculations, much as Malaysian shuttle diplomacy did during July’s shorter truce.
Thai diplomats quietly welcome the American nudge. Keeping the dispute bilateral but not isolated allows Bangkok to counter online narratives portraying Thailand as the aggressor. Foreign Ministry insiders say the United States could help “de-escalate nationalist rhetoric” by insisting that both sides stick to international humanitarian law.
What exactly is in the 27 December ceasefire?
The text, signed in Poipet before being flown to Aranyaprathet for a countersignature, freezes the conflict in place:
• All artillery, rockets and drones are grounded across the 817 km frontier.
• Both armies must stay in current positions—no reinforcements, no patrols beyond existing lines.
• Airspace incursions are banned, a clause aimed at Cambodian Su-25 attack jets that struck Sa Kaeo earlier this month.
• The two capitals agreed to invite ASEAN Observers on the Ground (AOTG) to verify compliance.
• If weapons stay silent for 72 hours, Thailand will hand back 18 Cambodian soldiers captured in July.
Military lawyers stress that the document is “an operational pause, not a peace treaty”. Border demarcation talks will resume under the long-stalled MOU 2543, but neither side concedes territory by signing.
Border towns count the financial scars
From Sa Kaeo’s Rong Kluea market to Oddar Meanchey’s O Smach casino strip, trade that once reached ฿300 billion a year has collapsed. Customs data show only ฿95.6 billion in cross-border commerce during the first ten months of 2025—a 36.68 % plunge. The Federation of Thai Industries puts daily losses at no less than ฿500 million, citing shuttered warehouses, ruined crops and transport insurance that has quadrupled.
Local leaders warn that a narrow focus on troop withdrawals will not revive livelihoods. “Merchants need safe highways, farmers need buyers, migrants need work permits,” says Prapat Nokhon, chairman of Sa Kaeo’s chamber of commerce. Even if guns stay silent, mine-clearing crews must sweep paddy fields before this dry season’s planting window closes in February.
Why experts doubt the danger has passed
Regional analysts interviewed by the Bangkok Post’s partner newsroom, SEAsia360, draw uncomfortable parallels with skirmishes around Preah Vihear in 2008–11. Their main concerns:
Unresolved maps – The colonial-era cartography dispute remains, making “no-man’s land” a perpetual flashpoint.
Rising nationalism – Social-media engagement on the conflict topped 1.26 billion interactions, meaning leaders face real-time pressure from keyboard warriors.
Economic incentives for hardliners – Smuggling syndicates and so-called “grey-zone” security firms profit from chaos.
“Unless both prime ministers sell the ceasefire domestically as a win, spoilers will test the line,” warns Assoc. Prof. Dulayapak Precharatch of Thammasat University.
The next 72 hours: markers of success or failure
Time is ticking. Here is what military and civil observers will watch between now and Tuesday noon:
• Zero incoming fire on the Thai provinces of Sa Kaeo, Surin and Si Sa Ket.
• ASEAN drones transmitting unedited footage of front-line artillery parks.
• Safe passage corridors for at least 10 convoys of displaced villagers returning home.
• Joint press briefings from Bangkok and Phnom Penh—any contradictory messaging is a red flag.
• The high-profile handover of POWs at Chong Chom checkpoint precisely 72 hours after guns fell silent.
If these boxes are ticked, negotiators will reconvene in January to tackle the deeper, thornier question: how to redraw a border without reigniting old grudges. For residents of Thailand’s eastern provinces, the hope is simple—let this be the last time children fall asleep to the sound of artillery on the horizon.
