The website's chief executive officer has dropped the hint amid the wave of Chinese Internet companies who have been going public in recent months.

A $2 billion dollar IPO would be big, even by the standards of recent Chinese listings.

360buy rival Dangdang only raised $272 million from investors ahead of its December listing on the New York Stock Exchange.

Founded in 2004 with a business model similar to Amazon.com, 360buy sells a broad range of products, such as electronics and cosmetics.
