Chinese shares opened lower on Friday as a sharp rise in oil prices rattled investor sentiment.
The Shanghai Composite Index, the main gauge of Chinese stocks, opened 0.6% lower at 3,910.92. The Shenzhen Component Index fell 1.0% to 13,483.63.
The retreat followed a surge in crude prices, with benchmark Brent crude hitting $109.20 a barrel on Thursday after the largest escalation in attacks on Gulf shipping since the U.S.-Israel conflict with Iran started, fueling worries among traders about additional supply interruptions.
