In the first four months of 2025, Thailand’s foreign investment surged by 43%, a leap fueled largely by the Eastern Economic Corridor (EEC). The EEC alone attracted $959 million, accounting for 54% of all foreign direct investment into the country. This massive inflow marks EEC Thailand 2025 as a defining force in regional industrial growth.
Covering over 1.3 million hectares across Rayong, Chonburi, and Chachoengsao, the EEC is Thailand’s government-backed zone for high-tech development, smart infrastructure, and advanced manufacturing. With over $50 billion committed from public and private sectors, the EEC is built to be more than just an industrial park. It is the nation’s vision for the future.
