Background
The Ministry of Culture and Fine Arts is the Cambodian authority that administers protection of archaeological sites and represents Cambodia’s cultural claims in interstate heritage and border dialogues. The ministry issued a formal statement on 13 May 2026 rejecting the Department of Fine Arts of Thailand’s registration of multiple temple sites claimed to be located within Cambodian territory.
Cambodia cited the Franco-Siamese Treaty of 1907 and existing bilateral mechanisms — including the 2000 Memorandum of Understanding (MoU), the 2003 Terms of Reference (TOR), and the Joint Border Commission (JBC) — as the proper frameworks for resolving disputes over boundary and heritage claims. The ministry stated that unilateral national heritage listings cannot be used as legal evidence to assert territorial sovereignty or to delimit international boundaries.
Key Developments
On 13 May 2026 the Ministry of Culture and Fine Arts issued a public protest and demanded that Thailand cancel registrations of archaeological sites that Cambodia contends lie within its sovereign territory. The ministry named specific temple sites in its statement (Khmer: ប្រាសាទតាមាន់, ប្រាសាទតាក្របី, ប្រាសាទខ្នារ) and described the Thai registrations as legally unfounded and without binding legal effect.
Policy Context
Both countries have used historical treaties and bilateral instruments to address boundary questions arising from colonial-era arrangements and subsequent surveys. Cambodia referenced those instruments to emphasize that heritage inventories do not substitute for the legal and technical processes established for boundary delimitation.
Institutional Role
The ministry framed its objection as part of its mandate to safeguard immovable cultural heritage and to coordinate with diplomatic and border authorities when heritage claims intersect with sovereignty issues. It formally called on the Royal Government of Thailand to withdraw the contested listings and to refrain from unilateral actions that affect ongoing bilateral efforts to resolve remaining disputes peacefully.
