Eastern Economic Corridor Office of Thailand (EECO)

The Eastern Economic Corridor Office of Thailand is the government agency responsible for coordinating development of the Eastern Economic Corridor, a major industrial and investment region covering Chachoengsao, Chonburi and Rayong provinces. The EECO was formally created under the Eastern Economic Corridor Act of 2018. It coordinates investment promotion, infrastructure planning, land use, public-private partnerships, innovation and advanced technology development within the corridor. The agency acts as an investment facilitator while overseeing strategic infrastructure and utilities needed to support industrial expansion. Its responsibilities are increasingly linked to sustainability issues, including water availability, resilient infrastructure, resource management, and the environmental impacts of rapid industrial growth.
