Ko Kut, located in Trat Province, lies about 35 km off Thailand’s eastern coast in the Gulf of Thailand. It is a large island with both geological and strategic significance, especially in the context of the Overlapping Claims Area (OCA) — a 26,000–27,000 sq. km. disputed maritime zone claimed by both Thailand and Cambodia.
Though the National Energy Plan 2024 currently excludes energy development in the OCA due to lack of a formal agreement, Ko Kut remains central to Thailand’s sovereignty and future energy security.
Under the 1907 Franco-Siamese Treaty, Ko Kut was recognized as Thai territory. Today, it continues to represent a symbolic “red line” for Thai nationalists. Any energy agreement on the OCA that potentially compromises Ko Kut’s status would be politically explosive.
By excluding the OCA from its current energy plan, Thailand signals its unwavering sovereignty over Ko Kut, despite Cambodia’s push for joint claims.
Proximity to OCA Energy Reserves
OCA is estimated to hold:
10–11 trillion cubic feet of natural gas
~300 million barrels of oil
Ko Kut could serve as:
A base for joint exploration
A hub for pipeline routes or energy infrastructure development
Geological Value
Fossil evidence indicates Ko Kut was once part of an ancient freshwater basin during the Early Cretaceous (~130 million years ago)
Finds include:
Fossilized shark teeth, crocodiles, and dinosaur remains (e.g., Spinosaurid and Sauropod species)
Links to the Khorat Basin, one of Thailand’s main geological formations
Negotiating energy development in the OCA requires balancing:
National sovereignty concerns (especially regarding Ko Kut)
Energy needs and economic opportunity
A Joint Development Area (JDA) agreement that respects Thai sovereignty could unlock vast energy resources while reducing tensions with Cambodia.
While Ko Kut is not directly listed in Thailand’s National Energy Plan 2024 due to OCA-related disputes, its strategic importance remains immense:
Symbol of national sovereignty
Scientific value for geology and paleontology
Gateway for future offshore energy infrastructure, should cooperation with Cambodia move forward
Increase renewable energy share to 51% by 2037
Reduce reliance on imported gas
Invest in:
Small Modular Reactors (SMRs)
Floating solar power
New offshore explorations (in the Andaman Sea and OCA)
Ko Kut may well become a linchpin in Thailand’s sustainable and independent energy future, as it bridges scientific heritage, national security, and regional energy strategy.
