A range of statistics and corporate developments show Chinese direct investment in Thailand undergoing a structural shift — moving away from traditional manufacturing and toward high-value, emerging sectors such as data centers, AI computing hubs, electric-vehicle components, humanoid-robot parts, and advanced printed circuit boards (PCBs). The most closely watched development is the latest investment move by a Thai subsidiary of ByteDance, the parent company of short-video platform TikTok.
The Board of Investment (BOI) has approved a TikTok-affiliated Thai unit to invest roughly 842 billion baht (about $26.2 billion) to expand its data-center business, adding servers and expanding data storage and processing capacity across Bangkok, Samut Prakan and Chachoengsao to meet rising digital-service demand and strengthen Thailand's position in regional digital infrastructure. It's worth noting that the verified figure is 842 billion baht — not the roughly 84.2 billion baht cited in some earlier reports, an order-of-magnitude discrepancy — making this TikTok's largest single investment in Thailand to date.
The project is the largest among a recent batch of BOI-approved investments worth roughly 958 billion baht (about $29 billion) in total; three of the six approved projects fall under data centers and data-hosting services, together worth about 913 billion baht — underscoring that digital infrastructure has become the leading category of foreign capital flowing into Thailand. Beyond the data-center business, TikTok has also committed to digital-literacy and e-commerce training programs aimed at small Thai businesses and the local workforce, as a social-benefit component of the investment.
Beyond digital infrastructure, Chinese capital has recently spread into specialized manufacturing segments such as EV components, humanoid-robot parts and advanced PCBs, suggesting Chinese supply chains are deliberately building out a more complete supporting ecosystem in Thailand rather than using it solely for vehicle assembly or end-stage manufacturing. Industry analysts link the trend to faster technology cycles in China's own EV and robotics industries and their growing need to expand overseas, matched by Thailand's continuously refined foreign-investment access and tax-incentive policies in recent years.
Analysts also caution that this rapid upgrade in investment structure raises the bar for Thailand's supporting capacity — whether power and cooling infrastructure can sustain large-scale data-center operations, and whether the domestic technical talent pool can meet demand from AI and robotics industries, will directly affect how well this new wave of investment actually lands. That concern echoes Prime Minister Anutin's recent emphasis on "technology transfer" and "local supply-chain use," offering an important clue to where Thailand-China economic cooperation heads next.
On the manufacturing side, Chinese automakers' local production in Thailand has already reached meaningful scale. BYD's Rayong plant, operating since July 2024, has a designed capacity of 150,000 vehicles a year and had delivered more than 100,000 cumulative units by October 2025, currently assembling models including the Atto 3 (Yuan Plus), Dolphin, Seal, Seal 05 DM-i and Song Plus DM-i. GWM's Rayong factory has capacity for 80,000 vehicles a year and announced in late July 2026 that it had become the first automaker to complete local-production requirements offsetting import quotas under the EV3.5 scheme ahead of the program's deadline. A joint venture between SAIC Motor and Thailand's Charoen Pokphand Group in Chonburi produces combustion and plug-in hybrid models such as the MG5 and MG ZS, alongside battery-electric models like the MG S5 and MG4, which have begun production but not yet large-scale export. Seven major Chinese automakers now have local production in Thailand, with combined capacity exceeding 550,000 vehicles a year, making the country a key pillar in the Chinese EV supply chain's expansion into Southeast Asia.
