Cambodia escalates border tensions with legal move to ICJ after deadly clash
🕊️ What Happened?
On 15 June 2025, Cambodia officially submitted a request to the International Court of Justice (ICJ) in The Hague to resolve longstanding border disputes with Thailand, following a deadly skirmish on 28 May that resulted in the death of a Cambodian soldier along their 820 km undemarcated frontier
🇰🇭 Cambodia’s Position
Prime Minister Hun Manet emphasized the need for a peaceful resolution through “international law” via the ICJ
Cambodia has formally proposed that both nations jointly submit four contested areas to the court, citing high risks of military clashes
Phnom Penh has also imposed sanctions on Thai imports—electricity, internet services, and TV broadcasts—while halting them from its side
🇹🇭 Thailand’s Response
Bangkok has not accepted ICJ jurisdiction, preferring to continue bilateral negotiations, and has not replied formally to Cambodia’s submission
Thai authorities reaffirmed commitment to maintain dialogue through the Joint Boundary Commission, with the next round of talks scheduled for September in Thailand
🔍 Why It Matters
This marks a significant shift: Cambodia turning to a legal route after bilateral efforts didn’t resolve tensions.
A deadly clash on 28 May highlighted the volatility of the current status quo
The four disputed zones—including the area near the fatal incident—are now being pushed toward an international adjudication
🌐 Regional & Historical Context
The ICJ previously ruled in Cambodia’s favor in 1962 and 2013 over Preah Vihear temple, making this a historical continuation
Military build-ups occurred after the May clash, but June 14 talks achieved a tense de-escalation
🧩 What Comes Next?
Cambodia will proceed unilaterally if Thailand refuses jurisdiction, hoping for a court ruling that could override stalemate
Thailand may increase military readiness, but domestic and regional pressure is pushing for peaceful engagement .
