It wasn’t immediately clear what caused the sudden declines. Some investors pointed to an earlier commentary listed in a social media account affiliated with state broadcaster CCTV, which said that “the US should realistically view the progress made and revoke negative measures against China.” Beijing is earnest about trade talks with the US but is at the same time principled, it added.
Chinese stocks slid suddenly on Tuesday, showing that investors remain on edge as the second day of trade talks with the US gets underway.
A gauge of Chinese shares in Hong Kong fell as much as 0.9% as trading resumed after the mid-day break, and finished the session down 0.2%. It had risen as much as 0.5% earlier. The CSI 300 Index, a benchmark for onshore equities, flipped to a loss to end 0.5% lower.
