PATTAYA, Thailand – The Eastern Economic Corridor (EEC) Office has not accepted U-Tapao International Aviation Co. Ltd. (UTA)’s proposed downsizing of Phase 1 of the U-Tapao Airport project to a capacity of just 3 million passengers per year—down from the originally planned 12 million. The EEC deems the reduced size too small to serve as a true regional aviation hub.
Although the original Notice to Proceed (NTP) was set for July 31, 2025, the EEC has officially requested an extension from UTA, pending cabinet discussion on August 5. The delay stems from continued uncertainties over the high-speed rail project connecting three major airports (Don Mueang–Suvarnabhumi–U-Tapao), which was a key prerequisite for the airport project.
Negotiations have been ongoing since 2018, when the project was first proposed. UTA’s downsizing plan was made in response to these rail delays, but EEC insists on a comprehensive development approach and is asking how UTA will adjust if the high-speed rail becomes operational in the future.
Meanwhile, a revised joint venture contract for the rail project is under final review by the Office of the Attorney General. The State Railway of Thailand (SRT) and CP Group–led Asia Era One consortium are expected to conclude their discussions soon.
Deputy PM and Finance Minister Pichai Chunhavajira said any decision to cancel or continue the U-Tapao project must carefully consider the broader economic impact. Transport Minister Suriya Juangroongruangkit added that the rail contract revision should be finalized within 2–3 months.
