Cambodia has announced plans to unilaterally bring a decades-old border dispute with Thailand to the International Court of Justice (ICJ), despite ongoing diplomatic talks aimed at easing military tensions. The move follows a fatal skirmish in late May that reignited concerns over potential armed clashes between the Southeast Asian neighbors.
Both countries mobilized troops along their shared 820-kilometer border after a Cambodian soldier was killed near contested zones housing ancient temples. Cambodian Prime Minister Hun Manet confirmed on Friday that Phnom Penh will formally submit its case to the ICJ on June 15, 2025, targeting four disputed areas: Mom Bei, Ta Moan Thom Temple, Ta Moan Tauch Temple, and Ta Krabei Temple.
"Even if the Thai side refuses or remains silent, Cambodia will proceed unilaterally," Hun Manet stated, emphasizing his government\u2019s resolve. Thailand, however, maintains its preference for bilateral negotiations. Prime Minister Paetongtarn Shinawatra reiterated on social media that Bangkok seeks "a peaceful resolution through dialogue."
Analysts note the temples at the heart of the dispute hold both cultural significance and strategic value, with undemarcated borders complicating sovereignty claims. A weekend meeting of the Joint Boundary Commission in Phnom Penh yielded no immediate breakthrough, underscoring the fragility of cross-border relations.
The escalation highlights broader challenges in ASEAN regional diplomacy, where historical grievances and competing national interests often collide. While military conflict remains unlikely, the ICJ filing could set a precedent for resolving territorial disputes in the region.
