THMAR DA, PURSAT — Tensions between Cambodia and Thailand reached a new peak on Saturday morning, February 7, 2026. Cambodian authorities have officially accused Thai military units of a “serious violation of sovereignty” after troops allegedly placed heavy shipping containers and barbed wire across National Road 55 in Pursat province.
The blockade, located in Thmar Da commune, Veal Veng district, effectively severs a vital transport route and encroaches on Cambodian territory. According to AKP, this move constitutes a direct breach of international law and existing bilateral agreements, including the ceasefire reached just weeks ago on December 27, 2025.

Why This Matters to the West (US & UK) For the US and UK diplomatic communities, this escalation represents a significant threat to Southeast Asian stability. According to AKP, the blockade is not just a territorial dispute but a humanitarian crisis, as it traps thousands of displaced civilians. Prolonged instability along this border could disrupt regional trade routes and energy projects, which are vital for Western-backed development in the Mekong sub-region.
Strategic Analysis: The Failure of Unilateralism The Royal Government of Cambodia has remained firm in its commitment to a peaceful resolution. However, the repeated placement of obstacles by Thai forces suggests a breakdown in military-to-military communication. For Western observers, the situation in Pursat serves as a reminder that territorial integrity remains a sensitive “flashpoint” in ASEAN diplomacy.
