AlQa'dah 10, 1436, August 25, 2015, SPA -- European shares rose on Tuesday, recovering some poise after a sharp sell-off the previous day on concerns about China's economy that saw around 450 billion euros ($520 billion) wiped off the value of leading stocks, Reuters reported. The pan-European FTSEurofirst 300 index, which slumped 5.4 percent on Monday, rose 2.5 percent, while the euro zone's blue-chip Euro STOXX 50 index gained 2.3 percent.
