The China-based Alibaba Group has appointed a former U.S. federal prosecutor, Matthew Bassiur, to lead a team that will work to enforce intellectual property protection at the company, in cooperation with international brands and retail partners, industry associations, government regulators, law enforcement agencies and other organizations. The move follows renewed criticism by U.S. trade authorities that Alibaba, the world's largest e-commerce corporation, is not moving fast enough to eliminate counterfeit products and their sellers from its websites, including Taobao and Tmall. Bassiur led major anti-counterfeiting programs at Apple Computer and Pfizer after working in the Computer Crime & Intellectual Property Section (CCIPS) of the U.S. Department of Justice.
