As many as 9,700 articles emanating from more than 500 social media accounts were posted on various online platforms in China to attack Alibaba, mostly before the Singles' Day online shopping gala on November 11, according to a WeChat post on Wednesday by Alibaba's legal adviser. Up to 4,600 of these accused Alibaba of forcing merchants to choose sides or accusing it of monopolising China's e-commerce market.
At stake is an e-commerce industry that has dwarfed every other country in the world, and is being dominated by two large companies.
Alibaba's Tmall platform has 80 per cent share of China's online clothing sales, while JD holds 10 per cent, according to research by Analysys.
Even though Alibaba hadn't named the perpetrator of the online campaign, the company's legal adviser had forwarded Weibo posts that claimed JD as the client behind a 2.6 million yuan (US$394,000) contract to hire ChinaLabs, a Beijing-based consulting services provider, to attack Alibaba of monopolising the market.
JD paid ChinaLabs 600,000 yuan to initiate research and host media seminars to discuss Alibaba's monopoly in China's e-commerce market, according to the posts, which cited a contract between the two parties between August 1 and December 31.
Another contract showed that ChinaLabs was receiving 2 million yuan from JD to instigate China's antitrust regulators to investigate on Alibaba for monopolistic practices.
The contracts in the Alibaba legal adviser's posts could not be independently verified.
Spokespersons at JD, an online retail platform whose market value is about a tenth of Alibaba's capitalisation, did not respond to text messages and phone calls soliciting their comment.
Jincheng Tongda Law Firm, acting on behalf of JD, issued a statement on Saturday denying any association with ChinaLabs.
Separately, ChinaLabs' chairman Fang Xingdong denied through a Weibo post that his company had ever signed the contracts with JD, saying that it will continue to conduct investigations and research on the antitrust situation in China's e-commerce industry.
Alibaba's shares have doubled this year as the Hangzhou-based company broke its November 11 retail festival record and deepened its push to marry online and physical shopping. The company this month agreed to buy a 36 per cent stake in Hong Kong-listed Sun Art Retail Group, which runs one of the biggest hypermarket chains in China.
