"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," the firm said in a statement.

Alibaba runs China's largest online retailer, Taobao, and China's largest e-commerce website Alibaba.com
