BEIJING, May 31 (Xinhua) -- There are now more than 500 million 4G users in China thanks to government measures, a minister told a conference Tuesday.

China owns the world's largest 4G network with more than 2 million 4G base stations, Industry and Information Technology Minister Miao Wei told the First Global 5G Event in Beijing.
