Cambodian Prime Minister Hun Manet has submitted a formal appeal to the United Nations Security Council, urging urgent intervention in response to what he described as a “deliberate act of military aggression” by Thai forces along the shared border with Cambodia, according to Khmer Times. 

In a letter addressed to Ambassador Asim Iftikhar Ahmad, Pakistan’s Permanent Representative to the UN and current President of the Security Council for July 2025, the Cambodian leader outlined a series of alleged Thai offensives that began earlier today. The reported attacks targeted multiple sites, including Ta Moan Thom Temple, Ta Krabey Temple, and the Mom Bei area, situated within Cambodia’s Preah Vihear and Oddar Meanchey provinces.

Prime Minister Hun Manet strongly condemned the Thai actions, describing them as “unprovoked and premeditated aggression,” and denounced them as a clear breach of international law and a violation of the principles upheld by the United Nations and ASEAN Charters.

He affirmed that Cambodian forces had acted in self-defence to protect national sovereignty and territorial integrity, and called for an immediate end to hostilities.

The letter demands that Thailand “cease all military activities without delay, withdraw its troops to its own territory, and refrain from any further provocative conduct.”

The Prime Minister also referenced historical agreements, including the 1904 Franco-Siamese Convention, the 1907 Treaty, and the 2000 Memorandum of Understanding (MOU-2000), as the legal foundation for Cambodia’s position on the border dispute. He criticised Thailand for allegedly altering maps unilaterally in violation of these agreements and using those altered maps to support accusations regarding recent landmine incidents.

“It is deeply regrettable that this act of aggression comes at a time when Cambodia is actively engaged in lawful and peaceful measures to resolve border issues,” Hun Manet stated.

He reminded the Council that on June 2, 2025, the Cambodian government officially referred four disputed areas, Mom Bei, Ta Moan Thom Temple, Ta Moan Touch Temple, and Ta Krabey Temple, to the International Court of Justice (ICJ) for resolution. Despite this diplomatic step, he said, Thailand has continued to heighten tensions and ignored repeated appeals for restraint, including those made in the lead-up to the Joint Boundary Commission (JBC) meeting hosted by Cambodia on June 14-15.

Prime Minister Hun Manet called upon the Security Council to convene an emergency session to address Thailand’s actions and requested that his letter be circulated as an official UN Security Council document.
