SHANGHAI: China stocks closed up on Thursday, hovering near its highest level in more than three years, as investors remained bullish on AI plays despite concerns over potential US restrictions on Chinese innovative drugs.
China’s blue-chip CSI300 Index ended up 2.3 percent near its highest level since March 2022, while the Shanghai Composite Index gained 1.7 percent. Hong Kong’s benchmark Hang Seng index edged 0.4 percent lower.
Onshore AI shares jumped 6.8 percent, their largest single-day gain since October 18, 2024, with sector bellwether Cambricon Technologies surging 9 percent.
Shares of optical module giants Zhongji Innolight and Eoptolink Technology climbed 14 percent and 13 percent, respectively.

The draft targeting Chinese innovative drugs is unlikely to be implemented in practice, analysts at Orient Securities said in a note to investors, citing challenges such as restricting patients from accessing more effective treatments. “A previous bill targeting Chinese CROs (Contract Research Organizations), such as WuXi AppTec, also failed to be effectively enforced.”
