A rare public clash has broken out between Alibaba and Chinese authorities over the authenticity of the goods sold on the e-commerce giant's sites.
In an unusually strongly worded white paper, the State Administration of Industry and Commerce said many of the products sold on Alibaba's websites were substandard, violated trademarks or were illegal. The release of the documents comes less than a week after the agency unveiled a survey which found that only 37.25 percent of the goods the authorities examined on Taobao were genuine.
After the survey, Alibaba's Taobao posted an open letter on its official social media Weibo account refuting the agency's findings and questioning the sampling methods. The SAIC fired back with the white paper criticizing Taobao for lax internal controls. The paper was dated July 2014, showing the review had been conducted before the company's $25 billion IPO in September.
On its Weibo account, Taobao said it is also a victim.
"Fake goods are a tumor in economic development," the company said. "We are willing to work with departments to get rid of this tumor."
The site said the online retailer would ramp up its fight against counterfeits with a new 300 person team.
In a separate statement issued to CNBC, Alibaba said, "We have a zero-tolerance policy toward counterfeits on our platforms. We will continue to refineand harness technological tools at our disposal to protect intellectual property rights, working together with brands, associations and government agencies."
The move addresses a long time complaint many international brands have had about Taobao about fakes sold on its site. It also highlights a concern among wary investors that the company is dogged by the unpredictability of Alibaba's relations with the government.
The government's moves have sparked a debate among Chinese consumers about the quality of the goods they buy online. Many are calling on the government to tighten supervision over Taobao. "Alibaba need to ensure better products and join in the fight so that it will create a much better environment," one online user wrote.
