China is considering export controls on AI technologies, including banning local companies from using TSMC, report claims

According to the Financial Times, China is considering expanding its technology export controls to include advanced AI models, training data, and overseas acquisitions of strategically important tech ... Read original →

Banning Chinese AI chip designers from using overseas foundries like TSMC would immediately sever access to 3nm and below nodes, forcing firms such as Huawei and Alibaba’s Pingtouge to rely on SMIC—yet without EUV, SMIC cannot reliably produce high-performance AI training chips, creating a 'design-capable but fabrication-constrained' bottleneck. While this bolsters data sovereignty and keeps model weights within China, it drastically inflates compliance costs, especially for ByteDance and Zhipu whose global cloud strategies and open-source ecosystems depend on cross-border infrastructure. The U.S. is likely to accelerate AI chip export restrictions and rally allies to block Chinese AI standards. TSMC faces revenue risk but remains irreplaceable short-term. Over the next 18 months, China’s AI sector may split into an insulated domestic loop and a shrinking global footprint—prioritizing control over competitiveness.
