Cambodia Affirms Internationally Recognized Borders, Rejects Use of Force

PHNOM PENH, Cambodia (Jan. 4, 2026) — The Cambodian government reaffirmed Monday that it recognizes only internationally agreed border lines and opposes any attempts to alter borders through force.

Government spokesperson Pen Bona said Cambodia strongly rejects Thailand’s continued military presence and operations in four Cambodian provinces.

“Cambodia firmly upholds the protection of the international border line with Thailand, as established by the Indo-China-Siam border commission,” Bouna said.

“We respect international law, the principle of an unchanged border line, the Franco-Siamese treaties, the boundary pillar records of the Indo-China-Siam Border Commission, and other relevant agreements.”

He emphasized that Cambodia and Thailand share internationally recognized land borders defined by maps produced under the 1904 Agreement and the 1907 Treaty.

He also noted the role of the Joint Mixed Commission on the Cambodia-Thailand Boundary, which was established to clarify the border line between agreed-upon pillars.

Bona said Cambodia remains committed to resolving the dispute peacefully and diplomatically, in line with international law. He reiterated that “the border line cannot be changed through the use of force.”

He added that Cambodia’s position enjoys strong support from the international community and expressed hope that global partners would encourage Thailand to resolve the issue in accordance with international law and existing agreements.
