Beijing - China's main stock market soared by nearly 4 per cent on Wednesday as the chance of a central bank interest hike was diminished when experts estimated inflation would continue to decline in June. 

The key Shanghai Composite Index, which tracks shares traded in local and foreign currency gained 3.75 per cent to close at 2,920.55. 

The smaller Shenzhen Component Index also gained 4.07 per cent and reached 1,0355.37 points at the end of trading. 

The surge on Wednesday continued a period of strong daily fluctuations amid an overall downward trend in China's inflated share prices, with many analysts expecting more volatility. (dpa)
