Chinese Stocks Fall to One-Year Low Amid New U.S. Chip Policy Concerns

Chinese stocks fell to a one-year low as technology shares slid amid uncertainty over U.S. chip policy and restrictions targeting Chinese optical firms. The CSI 300 dropped as much as 2.4%, with domestic chipmakers and optical-equipment companies among the biggest decliners. Reports that Beijing may allow companies to buy Nvidia’s newer chips raised concerns that access to U.S. technology could weaken demand for homegrown alternatives, while proposed U.S. limits on two Chinese optical firms added pressure. The selloff underscores the competing forces shaping China’s semiconductor sector: efforts to build domestic capacity alongside continued exposure to shifting trade and export policies.
Four U.S. senators introduced legislation on Friday that would designate Innolight and Eoptolink as restricted vendors for U.S. government procurement.
Global X Management investment strategist Billy Leung said the proposed restrictions’ direct earnings impact was limited, but showed that technology restrictions were proceeding separately from diplomacy; he also said the two-month U.S.-China trade truce “fell short of hopes.”
A separate report said OpenAI had paused work on frontier models, a development that added pressure to Asian chip stocks more broadly.
The selloff also reflected a longer period of weakness: the CSI 300 had fallen 8.6% in July, its worst monthly performance in a decade, amid global technology selling and profit-taking in domestic memory-chip makers.
