U.S. e-commerce giant Amazon.com Incs China unit will strengthen regulation of its online sales channels and has closed down a third-party store, the online retailer said on Thursday, after state media criticized Amazon and smaller local rival Dangdang for selling fake cosmetics. A report on China Central Television (CCTV) said that third-party sellers on Amazon and Dangdang were re-selling fake cosmetic products, some of which were sourced from local grey-market wholesalers. Consumer protection has moved up on the agenda in China after the country strengthened consumer rights laws last year, dragging local and international firms into the spotlight including Apple Inc, Nikon Corp and Wal-Mart Stores Inc. Amazons China unit said in a statement on its official microblog account that it was taking the 30-minute CCTV report extremely seriously and took a zero tolerance policy towards fake goods.
