Cambodia Experts Raise Alarm Over Thailand Ending Maritime Framework

PHNOM PENH, May 5, 2026 (KPT) — Cambodian analysts have criticised Thailand’s reported decision to withdraw from a long standing maritime agreement, warning it could undermine efforts to resolve overlapping sea claims peacefully and weaken established mechanisms for dialogue.

The reaction follows reports that Bangkok has approved the cancellation of the 2001 memorandum of understanding, which for more than two decades guided bilateral discussions on maritime boundaries.

Political analyst Kin Phea said the move signalled a shift away from dialogue based dispute resolution. “Thailand is choosing the ‘law of the jungle’, ignoring peaceful mechanisms,” he said, suggesting the decision reflected reliance on strength rather than legal processes.

He added Cambodia may need to pursue alternative measures under the United Nations Convention on the Law of the Sea (UNCLOS) to safeguard its sovereignty.

Another analyst, Yang Poeu, said the MoU and UNCLOS frameworks were closely aligned, both emphasising resolution of maritime disputes in accordance with international law.

He warned Thailand’s withdrawal risked creating confusion and weakening established processes.

Kung Phoak, Secretary of State at the Ministry of Foreign Affairs, cautioned that dismantling the MoU would remove a key bilateral mechanism enabling dialogue for more than two decades.

Government spokesman Pen Bona echoed the concern, saying a unilateral withdrawal would abandon the only framework both sides have used to address disputed areas in the Gulf of Thailand.

The 2001 MoU has long served as the basis for negotiations over overlapping maritime claims, reflecting cooperation between the two neighbours despite periodic tensions.
