Asian shares wobbled on Tuesday as crude oil prices slid on rekindled oversupply fears and after downbeat manufacturing data raised concerns about global momentum. MSCI’s broadest index of Asia-Pacific shares outside Japan was down 0.2 percent, while Japan’s Nikkei (.N225) slipped 0.7 percent. U.S. crude oil (CLc1) was down about 0.8 percent at $31.38 a barrel after skidding as much as 7 percent overnight, pressured by weak economic data from China, a U.S. forecast for mild weather and doubts suppliers would be able to agree on steps to address the global supply glut.
