Chinese equities touched a one-year low as technology shares fell after reports Beijing may allow Nvidia H200 purchases and US senators proposed restricting Chinese optical producers in federal procurement. The CSI 300 dropped as much as 2.4%, while Cambricon Technologies, GigaDevice Semiconductor, Zhongji Innolight and Eoptolink Technology each fell at least 5%. The developments renewed uncertainty over demand for domestic chips and the continued separation of technology policy from broader US-China diplomacy.
