"Chinese ecommerce giant Alibaba took 90 million counterfeit items offline and spent over 1 billion yuan ($160.7 million) fighting fake goods, from the beginning of 2013 to November this year."
The online company's announcement highlights its massive issue with so-called "knock-offs" and its efforts to clean up its act ahead of the company's record $25 billion initial public offering (IPO) in September.
"From Alibaba Group's perspective, we bear a serious responsibility in this fight against counterfeits," chief executive Jonathan Lu said in a statement, according to Reuters.
Analysts said that this is not an issue specific to Alibaba but spreads across many ecommerce platforms.
"It is a problem that is industry-wide. Any of the auction sites where you have a lot of different sellers from all around the world will have an issue with counterfeits," Neil Saunders, managing director of retail analysts Conlumino, told CNBC by phone.
