Key Questions Answered

Chinese shares dropped to a one-year low, with the CSI 300 Index falling up to 2.4%, driven by a technology selloff following reports that Beijing might allow purchases of Nvidia's new chips and proposed US sanctions targeting foreign optical producers like Zhongji Innolight and Eoptolink. Investor sentiment was also dampened by a sluggish broader market, lack of economic stimulus, and upcoming holidays.

Chipmakers Cambricon Technologies and GigaDevice Semiconductor, alongside optical companies Zhongji Innolight and Eoptolink Technology, were among the top decliners, each dropping at least 5%. The chip-heavy Star50 gauge recorded its largest decline in a month.

Four US senators introduced legislation that designated Zhongji Innolight Co. and Eoptolink Technology Inc. as restricted vendors for government procurement. Although the direct earnings impact is expected to be limited, the move signals that tech restrictions are operating separately from diplomatic tracks.
