Cambodia’s repeated violations of the Joint Declaration
on the outcomes of the meeting between Thailand and Cambodia

1. On 10 November 2025, Cambodia violated the Joint Declaration on the outcomes of the meeting between Thailand and Cambodia, which was signed on 26 October 2025 in Kuala Lumpur, Malaysia, by covertly laying new anti-personnel landmines within Thai territory in Huai Thamariya area, Kantharalak District, Si Sa Ket province. This incident resulted in one of the injured Thai soldiers being permanently disabled.

2. It is deeply regrettable that only two days after, the Cambodian side violated the Joint Declaration again. Cambodia opened fire into Thai territory in Ban Nong Ya Kaew, Khok Sung district, Sa Kaeo province, on 12 November 2025, to provoke a response by Thai military personnel who were compelled to take action to safeguard Thailand’s sovereignty and in self-defense, actions which were conducted in accordance with international law and the Rules of Engagement.

3. Thailand condemns the aforementioned incidents both initiated by the Cambodian side which clearly violate the Joint Declaration. The planting of landmines constitutes a breach of the obligations under the Anti-Personnel Mine Ban Convention (Ottawa Convention) to which Cambodia is a State Party. Thailand has sent a protest letter through Japan in its capacity as President of the Meeting of States Parties to the Convention, also requesting that the letter be circulated to all States Parties. Thailand is also sending a letter to the Secretary-General of the United Nations regarding this matter. Furthermore, during the armed clash at Ban Nong Ya Kaew, Cambodian forces initiated gunfire into Thai territory, which amounts to violation of Thailand’s sovereignty and territorial integrity.

4. Thailand’s actions are undertaken with transparency and fully adhere to international law and standards. To this end, Thailand has invited the ASEAN Observer Team (AOT) to inspect the area where both incidents took place. Thailand also reaffirms its commitment to implementing the Joint Declaration – a crucial milestone in reducing tensions and paving the way towards peace, which both sides have committed to achieve. However, Cambodia has repeatedly violated the Joint Declaration and sought to stage incidents and fabricate false information. Such actions reflect Cambodia’s lack of sincerity in pursuing peace.

5. Thailand wishes to express its sympathy to the families of those affected by the two incidents. In this regard, Thailand calls upon Cambodia to take responsibility, conduct a transparent investigation into the incidents, cease provocative actions, and return to the path of peace in order to reduce tensions and prevent future losses.
