The benchmark Shanghai Composite Index tumbled 5.33 percent, or 130.74 points, to 2,319.87. The Shenzhen Component Index closed at 7,833.09 points, down 400.32 points, or 4.86 percent.

Aggregate turnover rose to 52.39 billion yuan ($7.62 billion) from 47.19 billion yuan on Friday.

Losses outnumbered gains by 810-12 in Shanghai and 650-19 in Shenzhen.
