Analysts are cautious about endorsing all the claims of China’s internet behemoths, and some are outright skeptical, reported the Financial Times. Last week, ecommerce group Alibaba announced that it had hit a target of Rmb3tn ($462bn) in annual sales, a number that is more than the entire US’s ecommerce market for 2015, and Didi Kuaidi, China’s largest internet ride-hailing platform, announced it had hit a milestone of 10m rides per day. But many industry watchers worry that the numbers are inflated for a variety of reasons – for example, by Alibaba sellers posting fake sales in order to boost their store rankings.
