The benchmark Shanghai Composite Index fell for the third day Wednesday amid concerns about a slowing economy.
But the index opened down only 0.24 per cent after plunging 3.52 per cent Tuesday to close at 3,005.17 points, veering toward the symbolic 3,000-point mark.
The smaller Shenzhen Component Index opened 0.43 per cent higher at 9,330.76 points and the ChiNext Index, which tracks tech and other growth companies, opened 0.9 per cent higher at 1,813.73 points.
The Shanghai exchange has suffered from high volatility in recent months, leading to a series of official measures aimed at stabilizing prices and reassuring investors about the strength of the Chinese economy.
Government statistics revealed Sunday that growth in industrial production was lower than expected, at 6.1 per cent.
