Asian shares struggled to recover on Thursday with volatility remaining high, while emerging economy and commodity-linked currencies softened as investors worried about the global repercussions of slower growth in China. Japan’s Nikkei rose for the first time in four days, gaining 0.7 percent. Many Asian bourses also advanced but weakness in Australia and falls in Asian currencies drove MSCI’s dollar-denominated broadest index of Asia-Pacific shares outside Japan down 0.2 percent.
