The Clause Thailand's Warning Needs Is Not in the Documents Both Signed
Thailand's deputy prime minister and foreign minister, Sihasak Phuangketkeow, told The Nation on 24 May 2026 that Cambodia's use of international platforms against Bangkok was undermining the effort to rebuild trust. He named a late-December 2025 joint statement as the instrument Cambodia's conduct contravened, describing it as one under which both countries had agreed to resolve problems through internal dialogue and avoid escalating bilateral issues on international platforms.
The actual 27 December 2025 Joint Statement of the 3rd Special General Border Committee, signed by Defence Minister Nattaphon Narkphanit and Deputy Prime Minister and Minister of National Defence Tea Seiha at 10:15, contains sixteen numbered operational paragraphs across two sections. None of those paragraphs directs either side to resolve problems exclusively through internal dialogue or to refrain from raising bilateral issues at international forums.
Three days before Sihasak's warning, on 21 May, Cambodia's permanent representative to the UN, Chhea Keo, addressed the UN Security Council open debate on the Protection of Civilians in Armed Conflict. Cambodia's official figure on civilian displacement from the July and December 2025 hostilities is 649,000, with more than 30,000 still unable to return home.
Two days after Sihasak's warning, on 26 May, Sihasak attends a UN Security Council open debate in New York, chaired by Chinese Foreign Minister Wang Yi under China's May presidency of the Council.
Sihasak's 24 May warning is his third in three months on the same theme. On 24 February in Geneva, he characterised Cambodia's UN engagement as "demonising Thailand" at the UN Human Rights Council. On 14 March he named Cambodia's referrals to the Security Council, UNESCO, and the International Court of Justice as moves that complicated the situation.
Thailand's own UN engagement on the same dispute over the same period: A/80/593-S/2026/37 filed at the Security Council on 19 January characterising Cambodia's conduct as "a clear violation of Article 2(4) of the Charter of the United Nations" and invoking Article 51 self-defence; Cherdchai Chaivaivid at the 26 January UNSC Rule of Law debate; Sihasak himself at the 24 February UNHRC Geneva session.
Sihasak served as fifth President of the UN Human Rights Council from 21 June 2010 to 20 June 2011 and held Thailand's Permanent Representative role at the UN Office at Geneva in the preceding years.
The KLPA paragraph 4 bullet, the GBC Joint Statement paragraphs 8 and 16, and the equivalent commitments in the ASEAN Chair statement and the Cebu Outcomes Statement each restrict content (false information, misinformation, harmful rhetoric). None restricts the use of international forums. The forum question and the content question are different questions; Sihasak's warning runs them together.
