Bulls help key index to sustain rebound

Stocks jumped with China's benchmark index entering a bull market after an unprecedented State rescue effort halted a $5 trillion slump and ordinary investors returned to the market.

The CSI300 index of the largest listed companies in Shanghai and Shenzhen increased 2.1 percent, to 3,705.97 points.

The benchmark Shanghai Composite Index gained 1.9 percent to 3,522.82 points, taking its advance from its Aug 26 low to more than 20 percent.
