Chinese stocks fell slightly on Wednesday after the central bank said it had injected liquidity to selected lenders, but analysts cautioned it could take time to recover from this week's falls.

The benchmark Shanghai Composite Index fell by 0.41 percent to 1951.50 on Wednesday with turnover shrinking to 80.9 billion yuan ($13.2 billion) from 104.7 billion yuan on Tuesday.

The People's Bank of China said on Tuesday evening that it has recently supported some financial institutions with liquidity to ease a cash crunch, adding that it will lend further support to stronger players if they face a shortage of funds going forward.
