"Western media, for the most part, has ignored a remarkable array of Chinese pilot products in industrial automation, executed primarily by Huawei, the world’s largest maker of telecommunications infrastructure and the target of a global suppression campaign by the United States. Fully automated factories, mines, ports, and warehouses already are in operation, and the first commercial autonomous taxi service is starting up in Beijing. Huawei officials say the company has 10,000 contracts for private 5G networks in China, including 6,000 in factories. Huawei’s cloud division has just launched a software platform designed to help Chinese businesses build proprietary AI systems using their own data.

There’s no indication that the Biden administration’s restrictions on high-end chips and the software and machines that make them have slowed China’s drive for dominance in the so-called Fourth Industrial Revolution—the application of AI to manufacturing, mining, farming, and logistics. Although the fog of tech war makes it hard to evaluate China’s progress with precision, available information points to surprisingly rapid progress in China’s efforts to work around technology restrictions.

China is leading in the application of AI and high-speed broadband to business productivity. This can have one of three outcomes:

1. The United States and its allies make a concerted effort to leapfrog China and reclaim technological leadership in industry;

2. America and Europe adopt Chinese industrial technology and become followers, as China was a follower of developed markets a generation ago;

3. America continues to lose market share in industry and increases its import dependency, following the United Kingdom’s path of industrial decline.

China’s Chip Dominance and the Failure of U.S. Tech Controls

Western analysts have overestimated the impact of technology controls on China, and underestimated China’s ability to work around them. There is a great deal of confusion about the importance of the latest generation of computer chips, whose narrow gate width allows more transistors to be packed into a single chip. The newest iPhones run on chips with 13 billion transistors; for reference, the computer that took the Apollo capsule to the moon in 1969 had about 64,000. The faster speed and energy efficiency of the newest chips are indispensable for 5G handsets. The graphics processing units (GPUs) produced by Nvidia and AMD make tractable the enormous datasets required for large language models (LLMs), like ChatGPT. But older chips, alone or working in parallel, can handle most business AI applications. More important than raw chip speed is the availability of the right data, the ability to transmit it quickly and conveniently, and the overall system architecture.

China Is Pushing Ahead on Tech, and It Shows

The United States and China approach AI differently. The trillion-dollar valuations of the great American technology companies mainly come from consumer entertainment. China, as Huawei’s Zhang said, has no time for poetry. Rather than guess when the machines will become sentient or when AI will replace human beings, China has focused on the automation of drudge work: inspecting parts on a factory conveyor belt, checking the bins near the coal face for foreign objects, detecting anomalies in machines, picking containers out of ships and placing them on autonomous trucks, and so forth.

China’s plan to assert leadership in the Fourth Industrial Revolution—the application of AI to production, logistics, and services—appears to be on track.

Except for large manufacturers who already maintain large-scale operations in China, American manufacturers have shown little commitment to Fourth Industrial Revolution technology.

Why Have U.S. Tech Sanctions Failed?

For several reasons, U.S. sanctions are ineffective in constraining AI development in China.

First, as noted, China’s home designs are competitive in industry applications, which typically require less computing power than LLMs and may already offer performance equivalent to the Nvidia and AMD offerings

Second, China’s SMIC can produce 7-nanometer chips, albeit with much higher costs and lower efficiency. It can certainly meet the requirements of China's military for 7-nanometer chips. These are probably quite small; existing military systems overwhelmingly use older chips, which are more robust and easier to harden, as the RAND Corporation explained in a 2022 study.

Third, Nvidia’s fastest AI chips are readily available in China through third-party sellers although at higher prices. Slower versions designed by Nvidia to stay within U.S. guidelines are still sold to China, although Washington reportedly may ban these as well.

Stopping Chinese firms from using American AI computing power via cloud services won’t accomplish much, according to US industry leaders. ...“Well, the reality is that there are some very strong cloud providers who are Chinese cloud providers in China. So Chinese companies in China are going to have access to AI capabilities, whether they come from U.S. companies, European companies, or Chinese companies.”

Compete Seriously or Perish
U.S. limits on technology exports to China do not appear to have stopped or even slowed the rollout of the AI applications that have the greatest strategic impact. At the same time, restrictions on sales to China reduce the revenues of U.S. semiconductor companies and endanger their R&D budgets.
....
Restrictions on technology exports to China at best are a stopgap. Eventually, China, which graduates more engineers each year than the rest of the world combined, will develop its own substitutes, as ASML, the world’s premier maker of chip lithography equipment, avers. Even as a stopgap, though, the controls are failing. They impose high costs on China in several ways but have not impeded the Fourth Industrial Revolution. On the contrary: the limited adoption of Fourth Industrial Revolution technologies by American industry is concentrated in firms that have major commitments to China.."
