China's largest e-commerce group Alibaba Group, in which Yahoo Inc owns a 40 percent stake, has called the search giant's comments on Google reckless.
Alibaba Group, which owns Taobao, China's largest online retailer and Alibaba.com, has had a testy relationship with Yahoo since the departure of its founder Jerry Yang.
Alibaba Group has communicated to Yahoo! that Yahoo's statement that it is 'aligned' with the position Google took last week was reckless given the lack of facts in evidence, said the firm in a statement.
Yahoo said last week it stood aligned with Google that attacks on company networks are deeply disturbing and violations of Internet user privacy is something that must be opposed.
Google said last Tuesday it may exit the China market after it suffered a sophisticated cyber-attack on its network.
