China's stocks saw their biggest losses in a month on Thursday, after the release of the disappointing PMI figures and Japan's worst equity plunge since 2011.

The benchmark Shanghai Composite Index slumped 1.16 percent to 2,275.67 points. Trade volume decreased to 111.1 billion yuan ($17.9 billion) from Wednesday's 115.3 billion yuan.

But analysts attributed the drop mainly to corrections in other Asian stock markets.
