Thailand and Cambodia Lock Horns Over Koh Kood as Energy Stakes Rise
Territorial dispute over resort island escalates amid fresh offshore resource ambitions and historical fault-lines
A renewed diplomatic standoff between Thailand and Cambodia has placed the picturesque Gulf of Thailand island of Koh Kood at the centre of their maritime dispute, as both countries re-evaluate offshore energy opportunities and deepen security postures.
The island, Thailand’s fourth-largest, may not yet rival Phuket or Koh Samui in tourist numbers — but its strategic importance has climbed sharply.
Bangkok maintains full sovereignty over Koh Kood, maintaining its status within Thailand’s Trat province.
Phnom Penh, however, contests parts of the island and the adjoining seabed, citing a reinterpretation of the 1907 Franco-Siamese Treaty and asserting that the island falls within its continental shelf claim.
This long-dormant claim has been revived amid pressure to exploit believed gas and oil reserves beneath the Gulf of Thailand, raising resource-sharing debates.
Energy concerns are becoming pivotal.
Exploration firms believe the offshore region around Koh Kood holds substantial reserves of hydrocarbons, and as both Thailand and Cambodia face rising import bills for energy, the island has moved from tourism isle to geopolitical fulcrum.
Analysts point out that while the prospect of resource extraction has brought urgency to Bangkok and Phnom Penh, the underlying dispute remains rooted in ambiguous colonial-era maps, legacy boundary definitions and overlapping continental shelf claims.
Thai nationalist sentiment has also sharpened the dispute.
For many in Thailand, any suggestion of shared sovereignty or diminished Thai control over Koh Kood is unacceptable.
Meanwhile, some observers flag concern that close personal ties between Thailand’s ruling family and Cambodia’s leadership may be influencing the pace and tone of negotiations.
Critics argue that transparency over the 2001 memorandum of understanding between Thailand and Cambodia — which proposed profit-sharing from oil and gas — remains lacking, feeding public suspicion.
Diplomatically, both countries have taken cautious steps.
Thailand has reiterated its preference for bilateral negotiation, rejecting third-party mediation, while Cambodia has called for international adjudication and warned that sovereignty compromises will not stand.
In Thailand’s parliament and media, the issue has become politically charged — and may yet shape broader foreign policy and defence priorities in the region.
The path ahead remains uncertain.
Unless Bangkok and Phnom Penh clarify the status of Koh Kood and agree a mechanism for resource sharing, analysts foresee a prolonged stalemate — with the possibility of flare-ups elsewhere along their maritime boundary.
For now, Koh Kood continues to sit quietly behind the palm trees, its appeal to tourists unchanged, but its strategic significance unmistakably higher than ever.
