Chinese optical component makers tumbled after Reuters reported the US is drafting restrictions on imports of data center components to safeguard AI infrastructure. Zhongji Innolight led the decline.

Zhongji Innolight and other Chinese optical stock makers faced sharp selloffs following the Reuters report detailing a proposed US import ban targeting certain data center components used in AI systems. The reported measure aims to protect US artificial intelligence infrastructure from potential vulnerabilities through Chinese supply chains. Optical components are critical to data center operations, making the sector a key target for trade restrictions. The proposal reflects escalating US efforts to limit Chinese access to advanced technology and infrastructure. If implemented, the ban would disrupt supply chains for companies dependent on Chinese optical manufacturers. Zhongji Innolight, a major supplier of optical transceivers and related components, experienced the steepest losses among affected stocks. The company derives significant revenue from data center clients globally. The draft status of the ban leaves room for negotiations and modifications before any final policy takes effect. Chinese manufacturers and US companies reliant on their components face uncertainty pending official announcement and implementation details.
