China is forecast to spend 900 billion yuan ($134 billion) to 1.5 trillion yuan ($224 billion) on 5G network construction from 2020 to 2025.

The spending will come as the country scrambles to commercialize fifth-generation communications technology, a think tank affiliated with the country's top industry regulator said on Monday.

China's telecom carriers are expected to generate 1.9 trillion yuan ($284 billion) in total revenue from 5G-related business during the same period, according to an article published by the China Academy of Information and Communications Technology.

The publication is affiliated with the Ministry of Industry and Information Technology.

During the initial stage of 5G network construction, telecom carriers will first cover China's most populated regions, while the work is expected to coordinate with existing 4G networks, the article said.
