Asian shares were mostly higher on Wednesday on hopes that Beijing could stem the rout in its markets without damage to the economy, though caution was the watchword ahead of a policy decision from the U.S. Federal Reserve. The steadier tone was enough to lift Australia’s main index (.AXJO) 1 percent, while MSCI’s broadest index of Asia-Pacific shares outside Japan bounced 0.7 percent. Japan’s Nikkei (.N225) was one of the few markets in the red with a loss of 0.4 percent.
