Chinese e-commerce giant Alibaba Group is back on the US government's annual list of "notorious markets" that sell pirated goods. The Office of the US Trade Representative said yesterday that Alibaba's on-line marketplace Taobao sells "high levels" of counterfeit goods and is slow to respond when companies complain about the knockoffs. USTR took Alibaba off the blacklist in 2012, but several US trade groups successfully sought to get it reinstated. Alibaba Group President Michael Evans said the company is "disappointed."
