The size of the Chinese Internet is staggering. There are almost 600 million Internet users in China now, more than in any country in the world — next highest is the U.S, with 254 million. That’s just 44% of the Chinese population compared to 81% in the U.S., so this gap will continue to grow. For example, if every province in China achieves a 50% penetration rate, 135 million new Internet users will come online. 78.5% of Chinese users access the web from their mobile devices (compared to 63% in the U.S.), and many of the most popular services, like WeChat, exist only as a mobile application.
