Chinas purchasing managers index, or PMI, has revealed its first gain in four months.
The purchasing managers index, which measures manufacturing growth, rose to 51.7 in August from 51.2 in July.
A separate HSBC survey also showed a rise, reaching a three-month high of 51.9 in August from 49.4 in July. Anything above 50 shows an expansion.
However, the benchmark Shanghai Composite Index fell despite the positive news.
The market fell 15.92 points, or 0.6%, closing at 2,622.88.
Commentators have suggested the drop was caused by continuing concerns about slowing Chinese economic growth in the long term.
