A senior Thai-Summit executive warns that Thailand's automotive supply-chain advantage—once the industry's backbone—is being neglected despite recent policy focus on EV and foreign investment. BOI data shows Thai private enterprises' investment share fell from 41% to 25%, while foreign direct investment rose to 57%. SME automotive companies faced a 93% collapse in promotion applications (14 projects in 2024 vs. 1 in 2025). The speaker urges the state to stop letting competition from Vietnam and Indonesia erode Thailand's core strength: its established parts-manufacturing ecosystem and supply-chain infrastructure.
