Chinese shares continued to plunge on Monday with the benchmark Shanghai Composite Index dipping 2.67 percent to end at 3,114.80 points.
The Shenzhen Component Index lost 6.55 percent to close at 9,778.23 points, Xinhua news agency reported.
The ChiNext Index, which tracks China's NASDAQ-style board of growth enterprises, lost 7.49 percent to close at 1,906.21 points.
Despite government reassurance about continued stabilisation of the market, concerns remain over lingering downward pressure in the economy.
China's value-added industrial output expanded 6.1 percent year on year in August, the National Bureau of Statistics (NBS) said on Sunday.
The growth rate was up slightly from six percent in July, but still fell short of market expectations.
