China's benchmark equity market rose slightly on Tuesday, after the central bank injected funds into the financial system via open-market operations for the first time in three weeks, in a bid to alleviate a cash crunch.

The benchmark Shanghai Composite Index rose 0.15 percent to 2,092.91 points at the close from a four-month low on Monday. Turnover was at 61.7 billion yuan ($10.1 billion), up from 58.4 billion yuan on Monday.

Analysts said the liquidity crunch was the major cause of a consecutive nine-day loss in the SCI in the last two weeks. Although the tight liquidity situation has been eased with the central bank's help, investors are pessimistic, as they believe that a long-term liquidity squeeze is still possible.
