The Government of Thailand has been investing THB1.34 trillion to build a smart city in Huai Yai, Chonburi, as part of the Eastern Economic Corridor (EEC) development. The project, also known as ‘Bangkok 2’, will span 14,619 rai (2,340 hectares) and is expected to be completed by 2037. The first phase (2025–2030) will cover 5,795 rai, with key facilities including basic infrastructure, business districts, wellness centres, and mixed-use commercial areas.

The city will support 350,000 residents and generate 200,000 jobs. It will focus on six sectors: finance, healthcare, international education, tourism, BCG industries, and residential development. Upcoming milestones include land clearance by 2027 and full private sector rollout by 2028. Officials aim to position the city among the world’s top 10 smart cities, using public-private partnerships (PPP) models and EEC investment incentives to attract global investors.
