Cambodia Says It Has Sent 42 Border Protest Notes to Thailand Since Ceasefire

PHNOM PENH, June 22, 2026 (KPT) – Cambodia’s Joint Boundary Commission has sent 42 diplomatic protest notes to Thailand since a ceasefire agreement took effect in July 2025, accusing Thai forces of carrying out activities inside Cambodian territory, officials said Monday.

Government spokesman Pen Bona said 32 of the notes were filed after a second ceasefire agreement was reached on December 27, 2025.

Cambodia also submitted nine diplomatic notes requesting a special JBC meeting and the deployment of Joint Survey Teams to resume stalled border survey work.

“Cambodia has been the only side to formally submit diplomatic protests since the agreements reached in late 2025,” Bona said, describing the notes as an important means of defending Cambodia’s territorial claims under international law.

He said the protests serve as legal documents to preserve Cambodia’s position in any future legal or diplomatic process.

Bona added that Cambodia’s requests were based on commitments contained in the minutes of a special JBC meeting in October 2025 and a General Border Committee joint statement in December.

He accused Thailand of continuing activities in areas Cambodia considers under illegal occupation, aimed at creating a “fait accompli” on the ground.

Reaffirming Cambodia’s stance, Bona said the government rejects any attempt to alter the border through force or unilateral action and remains committed to resolving disputes under international law.

He cited the principle of uti possidetis juris, Franco‑Siamese treaties, official maps and boundary records as the basis of Cambodia’s position.
