   Fighting between Thailand and Cambodia has intensified near the Ta Kwai temple in Surin, Thailand, involving artillery, airstrikes, and gunfire. The Cambodian government reports that two weeks of deadly border clashes have displaced more than half a million people.

   UN Conciliation Begins Amid Renewed Thai-Cambodian Border Violence

   Thailand and Cambodia have initiated UNCLOS conciliation proceedings in Singapore following a year of deadly land clashes and overlapping maritime claims. The United Nations chief has appealed for immediate de-escalation, restraint, and humanitarian protection in response to renewed airstrikes, violence, and civilian displacement. Simultaneously, Thailand has urged Cambodia to respect the December 27, 2025 ceasefire agreement and halt border provocations to improve bilateral relations. The Joint Boundary Commission previously convened in Phnom Penh on June 14 following a May 28 clash, though Cambodia excluded four areas currently before the International Court of Justice.

   Why it matters

   The two nations are leveraging international legal mechanisms to address unresolved territorial tensions that erupted into deadly violence throughout 2025. These legal steps unfold against a backdrop of disputed land zones, historical shelter populations, and ongoing disputes regarding information control in the region. Regional stability depends on whether bilateral diplomatic channels can hold alongside formal international arbitration.

   What is confirmed

   • Thailand and Cambodia turned to a conciliation commission constituted under the United Nations Convention on the Law of the Sea to resolve overlapping maritime claims.
   • The foreign ministers of Thailand and Cambodia delivered opening statements in Singapore on September 15.
   • Thailand urged Cambodia to honour the December 27, 2025 ceasefire agreement and refrain from border provocations.

   Still unconfirmed

   • Renewed airstrikes, violence, and civilian displacement have intensified along the border.
   • Phnom Penh hosted a Joint Boundary Commission meeting on June 14 following a May 28 clash, with Cambodia excluding four disputed areas now before the ICJ.

   • Developments regarding the four disputed areas currently before the International Court of Justice

   UN Hears Thai-Cambodian Territorial Claims as Border Tensions Persist

   Cambodia and Thailand pressed competing claims at the United Nations, addressing maritime boundaries under the UN Convention on the Law of the Sea alongside ongoing land disputes. Cambodia demanded a fair resolution and the resumption of boundary talks. Meanwhile, Thai officials reported ongoing ceasefire violations, troop incursions, and shelling in Si Sa Ket and Surin, while raising concerns over unresolved civilian presence in areas dating back to 1970s shelters. American officials warned that Cambodia is currently winning the international information war, as Thailand pushes for ASEAN-led monitoring to address alleged disinformation.

   Why it matters

Thousands of civilians remain displaced along the frontier due to landmines and militarized zones. Thailand postponed boundary talks, while Phnom Penh continues to push for a Joint Boundary Commission meeting.

   What is confirmed
