Thailand's Board of Investment (BOI) is coordinating with four state agencies to remove infrastructure bottlenecks and attract high-tech manufacturing to the Eastern Region. From 2023–mid-2026, the Eastern Region attracted 4,566 investment applications worth 2.6 trillion baht (50% of national total), with Chachoengsao, Rayong, and Prachuap Khiri Khan leading. BOI targets six sectors—biotech, electric vehicles, semiconductors, digital/AI, robotics, and advanced electronics—leveraging existing manufacturing bases and supply chains to position Thailand as a regional industry hub amid global geopolitical and supply-chain shifts.
