Thailand's 1.9% Q2 GDP growth—the weakest in Southeast Asia—is prompting government policy shifts to attract foreign investment tied to local supply chains and "Made in Thailand" standards. The Board of Investment and Finance Ministry are adjusting tax/excise measures and local content requirements across sectors (EVs, AI, green economy, financial hub) to ensure investments create domestic value over 3-5 years, not just capital inflow. Success hinges on whether mechanisms actually incentivize manufacturing and local production rather than simple import substitution.
