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.

In 2025, Chinese companies and researchers filed a record 22,031 patent applications with the European Patent Office, ranking China third behind the US and Germany for the first time. Huawei remained one of the largest applicants, with a 10 percent year-on-year increase in filings, ranking second behind Samsung. CATL climbed four places to 10th place, with filings up 12 percent. Other firms such as Xiaomi, ZTE, OPPO, and Tencent also ranked in the top 50. Overall, Chinese patent applications have tripled over the past decade, from 7,000 in 2016 to over 22,000 in 2025.
In tech applications, China filed the most patents in digital communications (21 percent), followed by electrical machinery (12 percent), computer technology (12 percent), and telecommunications (5 percent). The fewest applications were in biotech and medtech (3 percent each), as there was weaker interest in engine/pump technologies. Across all countries, computers, digital communications, electrical machinery, and medtech led tech applications. Semiconductor filings continued an upward trend (+7.6 percent), with the largest shares held by European and US applicants. Overall, 2025 showed a broad recovery and growth across the tech sector.

China is hoping to compete with US SpaceX’s Starlink, which operates in over 120 countries. Chinese provider SSST, which operates the SpaceSail constellation and is currently active in only six countries, aims to expand to at least 30 more by the end of this year, 2026. At the moment, no Chinese satellite internet provider can deliver broadband speeds to even a small number of users worldwide, though China is set to launch a huge number of internet satellites in the coming years.
