BEIJING, June 20 (Xinhua) -- Chinese shares slumped on Thursday after HSBC data showed that manufacturing activity fell to a nine-month low this month.
The benchmark Shanghai Composite Index fell 2.77 percent, or 59.43points, to end at 2,084.02. The Shenzhen Component Index declined 3.25 percent, or 273.76 points, to 8,147.48.
The HSBC Flash Manufacturing Purchasing Managers' Index (PMI) for June fell to 48.3, the lowest reading since October and down from 49.2 in May.
The tumble also tracked wide losses in Asian markets following news that the U.S. Federal Reserve could start scaling back its massive bond-buying program later this year if the U.S. economy improves as expected.
U.S. Federal Reserve Chairman Ben Bernanke said Wednesday that if U.S. data remain aligned with expectations for the economy, the central bank will reduce its pace of bond-buying "in measured steps" through the first half of next year and could end the purchases in 2014.
