Thailand is engaged in tripartite negotiations involving the State Railway of Thailand (SRT), Asia Era One, and the Eastern Economic Corridor (EEC) Office to address the future of the Airport Rail Link (ARL) and a high-speed rail project connecting three airports.

Asia Era One, a subsidiary of CP Group, has expressed intent to terminate its joint investment contract for the high-speed rail project and indicated it may cease ARL operations when the current agreement expires on September 30, 2026. The dispute regarding the 220-billion-baht high-speed railway project stems from disagreements over the payment structure; the company is pushing for a progress-based payment model rather than the current lump sum payment upon project completion.

Deputy Prime Minister Anutin Charnvirakul has warned that terminating the contract carries significant consequences. Under Prime Minister’s Office regulations, the consortium could be blacklisted for abandoning work and may be held responsible for any price differences if the project is re-tendered at a higher cost. 

To ensure service continuity, the SRT has proposed a one-year extension for ARL operations, though the consortium has not yet accepted. Asia Era One is expected to submit a management plan by September 4, with further negotiations scheduled for September 7. Additionally, the SRT has indicated it will take over construction for overlapping sections of the rail line. Officials plan to meet with the Secretary-General of the EEC to determine the next steps for the project and related regulations.
