'Nifty 50' in worst day in 6 months

SHANGHAI - Chinese mainland stocks fell on Wednesday, with the country's leading "nifty 50" stocks posting their worst day in six months.

Trading was thin, as investors awaited a likely US interest rate hike later in the session and debated whether China's central bank would follow with modest tightening of its own, as it did in March.

The blue-chip CSI300 index fell 1.3 percent to 3,535.30 points, while the Shanghai Composite Index closed down 0.7 percent at 3,130.67.
