China stocks ended lower on Wednesday as investors sought shelter after a global selloff in riskier assets amid increasing nervousness over a tightening US presidential race.

The blue-chip CSI300 index fell 0.8 percent to 3,333.35 points, while the Shanghai Composite Index lost 0.6 percent to 3,102.73.
