A new study by London-based international trade association GSMA shows that China will have the most 5G connections of any country by 2025.

The country will have 600 million 5G connections in five years' time, compared with more than 200 million in Europe and nearly 190 million in the US.

China's three major mobile operators — China Unicom, China Mobile, and China Telecom — are already moving ahead with 5G deployment.

While most countries will roll out 5G by updating their existing infrastructure, China plans to build part of its 5G networks from scratch.
