Chinese shares sank on November 10, sending the benchmark index to its biggest daily drop in almost three weeks, as the nation's export figures indicated a further slowing in global demand and rising Italian bond yields fueled concerns about eurozone debt crisis.

The benchmark Shanghai Composite Index fell 1.8 percent, or 45.38 points, to end at 2,479.54. The Shenzhen Component Index declined 1.4 percent, or 148.33 points, to finish at 10,477.55.
