BANGKOK, THAILAND – Thailand’s government faced renewed pressure to resolve a legal and financial rift over its 224-billion-baht high-speed rail project linking three major airports.
Cabinet to decide on disputed contract changes
On Saturday, Transport Minister Phiphat Ratchakitprakarn chaired an Eastern Economic Corridor (EEC) Policy Committee meeting in Bangkok with five key authorities, including the Office of the Attorney-General (OAG), the State Railway of Thailand, and Asia Era One Co Ltd. The session reviewed legal concerns surrounding Asia Era One’s request to revise its concession terms.
The private operator asked the government to switch from a fixed subsidy to a “pay-as-you-build” system tied to construction progress. Asia Era One said the adjustment would ease financial risks and speed up implementation.
Minister rejects payment model
Phiphat said the idea of flexible payments could potentially help unlock delays in the airport rail link connecting Don Mueang, Suvarnabhumi, and U-Tapao airports. However, he made clear he did not support the proposed payment format.
“I personally consider the proposed payment method inappropriate.”
said Phiphat Ratchakitprakarn, Transport Minister
According to the OAG, only events such as natural disasters, pandemics, or wars qualify under Clause 5 of the current contract as grounds for amendment. Legal advisers have yet to confirm if the company’s proposed change would be permissible.
Review deadline and legal warnings
The EEC Office was instructed to submit its written response to the OAG’s remarks by the end of the month. Phiphat stated he would present the matter to the Cabinet for a final ruling, stressing coordination with the Finance Ministry and Budget Bureau.
He said the decision must be reached before the planned dissolution of Parliament at the end of January 2026.
Risk of legal challenges
Phiphat reiterated his concerns that altering the concession could expose the state to lawsuits from losing bidders in the original tender. Those firms might claim the tender’s rules had been retroactively changed to favor the current concessionaire.
• Legal clarity remains a key prerequisite for the delayed 224-billion-baht high-speed rail project.
• The political timetable adds urgency, with Parliament nearing dissolution.
• Project delays threaten the long-term Eastern Economic Corridor infrastructure plan.
The Cabinet’s upcoming decision will determine whether one of Thailand’s largest transport ventures can move forward without triggering fresh legal disputes.
