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 2016, various domestic units formed an committee with one mission: Systematically replacing foreign technology from China’s IT systems, starting with government and military infrastructure and later moving to state-owned enterprises. The campaign that unfolded, known as “xinchuang” (信创, loosely translated as IT innovation) has nurtured domestic champions not only in hardware sectors, but also in software segments like databases, cloud services and operating systems.

China’s globally registered invention patents grew sharply in telecommunications from 2010 to 2021. China surpassed the US in 2016 and has maintained its leading position, but its growth seems to have plateaued, suggesting that innovation in slowing down. Patent publications have fallen slightly in the EU, despite being home to two of the largest equipment vendors in the world, Nokia and Ericsson, after starting at a level close to China and the US in 2011.

Between 2014 and 2018, many Chinese startups offered internet-based services, like the Internet of Things. With China’s tech crackdown of 2020-2021 and the reorientation of the economy toward the “real economy,” fewer startups focused on providing internet-enabled services.

Recent developments

Tech progress

  • Chinese telcos have launched the “Computing Power Internet” test network, part of a state-led national project spearheaded by the China Academy of Information and Communication Technology (CAICT), under the MIIT. The project aims to connect diverse, scattered computing resources via standardized identifiers and protocols, primarily to fuel AI development. (Source (CN): STDaily, May 17, 2025)
  • Zhejiang Lab has launched the first phase of a constellation of interconnected “computing satellites” for in-orbit data processing. With 100 satellites planned by 2027, this space-based computing network aims to bypass terrestrial data bottlenecks, enhancing connectivity and enabling near real-time insights for smart cities and disaster response, boosting space-to-ground digital infrastructure. (Source (CN) STDaily May 19, 2025)
  • Huawei launched its first personal computers running on its proprietary HarmonyOS, contributing to China’s xinchuang (信创) initiative to replace foreign technology. The launch completes Huawei's “all-scenario” ecosystem, integrating its mobile and PC platforms to create a unified domestic alternative to foreign competitors.

Domestic dynamics

  • Local governments are struggling to turn data centers into drivers of growth and innovation, despite subsidized electricity. In Zhongwei, one of the nationally designated computing power clusters and the “data warehouse” of Ningxia Province, tech giant Meituan uses 60-70 percent of its data processing and computing, but local officials complain about the limited impact on the development of local technology industries. (Source: (CN): China Environment News, May 9, 2025)
  • Beijing has officially elevated 6G to a national strategic priority, targeting commercialization around 2030. At this year’s “Two Sessions,” the concurrent sessions of the National People’s Congress (NPC) and the Chinese People's Political Consultative Conference (CPPCC), 6G made its first appearance in a Government Work Report. International standardization work has begun, and China is accumulating technical experience, with AI-native architectures and integrated space-air-ground networks envisioned to drive “new productive forces” and transform industries.  (Source (CN): 21Jingji, March 31, 2025)
