Chinese Internet retailer Dangdang.com has announced that the company has changed its management structure.

Additionally, Roger Huang, the chief operating officer at Chinese e-commerce firm Dangdang.com, has resigned due to personal reasons. His resignation was effective at the end of last month.

Of these, the daily commodities business department was newly established and is led by Dangdang.com’s vice president, Jiang Qiang, reporting directly to chief executive officer Li Guoqing.
