Digital connectivity
China’s government has long considered the internet essential infrastructure to upgrade its industry, boost competitiveness and for potential military uses. A combination of industrial policy, protectionism and entrepreneurship have led to the establishment of important telecommunications companies – chief among them, Huawei.
China was an early mover in 5G, currently the most modern mobile connection to the internet. Huawei and ZTE took part in early standardization meetings on 5G, and China deployed 5G in 2018, before most Western countries started their roll-out. Huawei’s technology rivals that of established equipment suppliers Nokia and Ericsson and is usually cheaper.
Now, the world is watching 6G, for which 2025 will be an important year. Huawei is already set to play an important role in this future key technology.
China’s strategy of building infrastructure first, assuming demand will follow, has worked very well especially in mobile and broadband internet. In disruptive internet technologies, this strategy is not possible. For instance, Chinese companies still trail the US satellite internet provider Starlink, which pioneered low Earth orbit (LEO), high-bandwidth satellite internet. China launched the first satellites in 2024 for Qianfan, an eventual globe-spanning internet network to rival Starlink, one of three networks intended to be operational in China by 2025.
Other technologies have seen less innovation in recent years but are still a focus of US-China tech competition. Submarine communications cables, for instance, have an average life cycle of 17 years, with recent innovation mostly focused on cost effectiveness. Since most traffic passes through submarine cables, both the US and China are wary about spying, and have thus competed for the location and control of many of these cables.

"Eastern Data, Western Computing" megaproject links up national resources
US export controls limit China’s access to hardware that can be used for computing. To deal with this scarcity through coordination, China’s government launched the National Integrated Computing Power network (NICPN). This is part of the “Eastern Data, Western Computing” plan that seeks to construct data centers in remote areas of China.
The EU and South Africa depend on Chinese digital connectivity equipment
As Chinese companies like Huawei started producing digital connectivity products like base stations, switches and routers, some countries now rely on Chinese equipment. While the US and India have managed to decrease their dependencies on China, South Africa and the EU have seen a significant increase in their reliance on Chinese equipment.
