Changes in Hong Kong stocks | Zhongji Xuchuang (03308) fell more than 5%, according to reports, US lawmakers proposed to ban Chinese optical modules

The Zhitong Finance App learned that Zhongji Xuchuang (03308) fell by more than 5%. As of press release, it fell 4.7% to HK$1,116, with a turnover of HK$196 million.

On the news side, bad news involving the optical module supply chain blew up the investment circle over the weekend. According to media reports, US senators from both parties proposed China's optical transceiver restriction bill on September 25. The bill proposes prohibiting the federal government from using Chinese light control modules in government systems involving sensitive information, and names Chinese suppliers such as Zhongji Xuchuang and Xinyisheng. Some analysts point out that the bill is still in the submission stage, and a five-year transition period is provided before the ban takes effect. China's high-end optical modules account for 70% of the world's share, and the short-term actual impact is limited.
