Asia stocks hit a 11-week low on Wednesday as renewed concerns about U.S. interest rates slugged Wall Street, while investors still smarted from dismal Chinese economic data and the absence of meaningful stimulus. MSCI's gauge of Asia Pacific stocks outside Japan was down 1.1% at 0138GMT, touching its lowest point since June 1. Japan's Nikkei 225 index slipped 1.3% to its lowest since July 12.
