Asian stocks turned in a mixed performance on Monday as weak Chinese data and anxiety ahead of this week’s FOMC meeting kept investors on edge. Investors took disappointing Chinese industrial output and fixed-asset investment data in their stride, although China’s stock-market ended deep in the red on doubts about Beijing’s ability to achieve its growth target of about 7 percent for 2015. Japanese shares also fell sharply as the dollar fell against the yen and the euro, heading into the Federal Reserve’s crucial meeting on Thursday.
