Hope on the Horizon, Thailand Cambodia Ceasefire
A tentative ceasefire between Thailand and Cambodia is scheduled to begin on December 27, 2025, following intense negotiations and a volatile month of renewed border clashes. This development aims to halt hostilities that have caused significant casualties and displaced hundreds of thousands of civilians.
The recent escalation in December 2025 followed a fragile ceasefire agreed upon in July 2025 and another brokered in October through the Kuala Lumpur Agreement, but fighting resumed with devastating consequences. The current focus is on sustaining peace and addressing the deep-rooted issues fueling decades of conflict.
The Road to the Thailand Cambodia Ceasefire December 27 2025
The path to this ceasefire involved three days of demanding discussions between Thai and Cambodian officials, culminating on December 26, 2025, in Thailand’s Chanthaburi province. These talks produced a sixth revised draft agreement, which awaits approval from Thailand’s National Security Council (NSC), chaired by Prime Minister Anutin Charnvirakul.
Preparations are underway for a potential signing ceremony on December 27, 2025, between Thailand’s Defence Minister Gen. Natthapol Nakpanich and Cambodia’s Defence Minister Gen. Tea Seiha. This ceremony is expected to formalize the ceasefire, which will be monitored for an initial 72-hour period. Prime Prime Minister Anutin has expressed hope for lasting peace and Thailand’s commitment to restoring regional stability.
A History of Volatility: Understanding the Border Dispute
The conflict stems from a long-standing territorial dispute rooted in colonial-era border demarcations, primarily concerning the ancient Hindu temple of Preah Vihear, a UNESCO World Heritage Site.
The dispute’s origins trace to the Franco-Siamese treaties of 1904 and 1907. While the 1904 treaty defined the border along the watershed, French maps from 1907 placed Preah Vihear on the Cambodian side. The International Court of Justice (ICJ) ruled in 1962 that the temple was under Cambodian sovereignty, based on the 1907 map, obligating Thailand to withdraw its forces.
Tensions resurged in 2008 when Cambodia sought UNESCO World Heritage status for Preah Vihear, leading to military clashes and nationalist protests. A 2013 ICJ clarification reaffirmed Cambodia’s sovereignty over the Preah Vihear promontory. However, ambiguities in surrounding undemarcated land continue to be flashpoints, contributing to recent escalations in 2025. Other contested areas include Prasat Ta Muen Thom and Prasat Ta Krabey.
The Human Cost of Conflict and Diplomatic Efforts in 2025
The renewed border conflict, intensifying in December 2025, has resulted in a severe human toll. By December 25, the total death toll reached 96, with Thai authorities reporting 23 soldiers and one civilian killed, plus 41 civilian deaths from “collateral effects.”
Cambodia’s Interior Ministry reported 31 Cambodian civilians killed and at least 13 soldiers dead in Preah Vihear province since December 8, with over 400 Cambodian soldiers and border police wounded.
The humanitarian crisis involves nearly a million displaced people. Cambodia’s Interior Ministry reported over 500,000 displaced, potentially reaching 610,000 by December 25. On the Thai side, over 150,000 people remain displaced.
Cambodia accused the Thai military of intensifying bombardment during peace talks. Cambodia also accused Thai forces of demolishing a statue of Lord Vishnu near Preah Vihear, which Thailand denied, stating the structure was not a registered religious site and was removed for security reasons.
The Kuala Lumpur Agreement and the Thailand Cambodia Ceasefire December 27 2025
The current diplomatic push for a December 27 ceasefire is framed by previous agreements, notably the Kuala Lumpur Agreement, a Joint Declaration signed on October 26, 2025, during the 47th ASEAN Summit. Witnessed by US President Donald Trump and Malaysian Prime Minister Anwar Ibrahim, this accord aimed to solidify a ceasefire and outline measures like phased withdrawal of heavy weaponry and joint humanitarian demining operations.
However, Thailand suspended this agreement in early November after Thai soldiers were injured by a landmine, leading to renewed clashes in December. Thai Prime Prime Minister Anutin Charnvirakul stated that current discussions align with the Kuala Lumpur Agreement’s four main points: withdrawal of heavy weapons, Thailand’s mine clearance efforts, suppression of scam networks, and resolution of issues in specific border areas (Ban Nong Chan and Ban Nong Ya Kaew). The Prime Prime Minister expressed a strong desire for this to be the “last time we sign” under this framework.
The Path Ahead: Challenges and Prospects for Lasting Peace
The scheduled Thailand Cambodia ceasefire December 27 2025 offers immediate relief, but a definitive, long-term resolution to the border dispute remains complex due to a history of broken ceasefires, divergent diplomatic approaches, and domestic political dynamics. Mistrust remains high, with mutual blame for escalating violence.
International mediation has been crucial. Malaysia, as ASEAN’s rotating chair, brokered an initial ceasefire in July. The United States, through President Donald Trump, supported peace statements, and China urged dialogue. These external pressures have been instrumental in bringing both parties to negotiations.
For enduring peace, sustained commitment to bilateral dialogue, potentially supported by coordinated international facilitation, is essential. This must comprehensively address underlying territorial claims and work towards mutually agreed-upon border demarcation. The ongoing talks between defense ministers under the Kuala Lumpur Agreement framework represent a crucial step, offering fragile but real hope for a future free from conflict.
