One EU official even warned that the European economy will be at risk due to its overreliance on American internet companies such as Google. In China, the monopoly position of Baidu, Alibaba and Tencent is self-evident. After Google left in 2010, Baidu cornered 70 per cent of the revenue in the search business in China; in e-commerce, Alibaba takes up 80 per cent of the online shopping revenue; and Tencent has 500 million active WeChat users and 815 million QQ users—about 60 per cent of the country's total population.
