China's stock market slumped for a ninth consecutive session on Friday - the longest losing streak in nearly 20 years - as investors worried about liquidity, despite central bank moves to ease pressure on the money markets.

The benchmark Shanghai Composite Index shed 2.02 percent to 2,084.79 points. Turnover remained relatively low, although it expanded to 72.2 billion yuan ($11.8 billion) from Thursday's 61.5 billion yuan.

The index has been dropping since last Tuesday, the longest losing streak since 1994, according to Bloomberg News.
