The Geography of the 2025 Cambodia-Thailand Border Conflict

One year after the initial fatal skirmishes and artillery exchanges during the summer of 2025, the Cambodia-Thailand border remains a highly volatile flashpoint in Southeast Asia. While active combat has paused under a ceasefire, the brief conflict resulted in significant geographic changes: legacy and newly laid anti-personnel landmines continue to disrupt production on important agricultural land, border infrastructure closures remain stiffly in place, and more than half a million civilians face protracted displacement. This analysis evaluates the military escalation along the Cambodia-Thailand border through a geospatial and environmental security lens, mapping the structural friction underlying the confrontation. By integrating historical cartography, terrain modeling, and satellite imagery, the study examines how a century-old French colonial mapping discrepancy along the Dângrêk Mountains’ natural watershed created overlapping territorial claims that modern legal frameworks have failed to reconcile. The research details how the region’s rugged escarpments, dense jungle corridors, and disputed cultural heritage sites like the Preah Vihear and Ta Muen Thom temples dictate local military maneuvers, transform historical architecture into tactical high ground, and amplify human displacement along critical logistical and environmental corridors.
