China Plus One
FDI Relocation Opportunities
US-China trade tensions accelerate China-Plus-One sourcing diversification. EEC positioned to capture electronics, auto-parts, and medical-device FDI relocation. BoI approved $21.7B+ in new FDI applications in 2023; EEC zone captures majority of high-value manufacturing inflows.
EV Transition
Automotive Electrification
Thailand targets 30% EV production share by 2030. Amata City and WHA estates investing in EV-supply-chain infrastructure: battery-module assembly zones, EV-charger deployment, and grid-upgrade investment to support higher power-demand profiles of EV factories.
Logistics
U-Tapao and Laem Chabang Expansion
U-Tapao Cargo City and Laem Chabang Port Phase 3 (60M TEU capacity target) are infrastructure multipliers for EEC cluster competitiveness. Construction timelines and concessionaire selection are key risks for industrial-estate investors.
