China's tech wall: Beijing locks up AI and solar know-how

<p><em>Special Reporting from LSN News, adapted from today's Asia Unfiltered episode. <a href="https://youtu.be/rdaSz1RFoK8" target="_blank" rel="noopener">Watch the video on YouTube.</a></em></p>

<p>Forty technologies. Fourteen proposed bans. Twenty-six new restrictions. On Friday, Beijing moved to wall off its most valuable know-how in artificial intelligence, biotech and solar power. Not the panels. Not the apps. The know-how. For factories from Gujarat to Indonesia, that distinction matters.</p>

<h2>Beijing's draft list</h2>

<p>On Friday, 16 October, China's Ministry of Commerce and Ministry of Science and Technology proposed adding 40 technologies to the list of technologies prohibited or restricted from export. Twenty-three are in artificial intelligence, covering large models, agents and computing clusters. Five are in biomedicine, including cell and gene therapy. Twelve are in solar manufacturing. The South China Morning Post and AFP report that 14 would be banned outright and 26 restricted.</p>

<p>Public comment runs until 15 November. But one part is already live: companies must now register exports of the listed technologies in advance, including deals already under way.</p>

<p>According to the Associated Press, Beijing would ban exports of core technology for large models trained on sensitive national data, and of AI agents designed for national defence and critical information infrastructure. Models with two trillion parameters or more could be restricted. Some AI and memory chip design technologies are also listed. Reuters reports that access through APIs, websites, apps and cloud services is excluded, and so is anything already open-source or published.</p>

<p>The commerce ministry said the aim is "reinforcing the security bottom line, preventing misuse and abuse, and ensuring that AI remains under human control." It called the revision routine and said it targets no country.</p>

<h2>The solar list, and why Asia is exposed</h2>

<p>The solar list is where Asia will feel it first. China would ban exports of technology for ultra-thin wafers of 70 micrometres or less, for high-efficiency perovskite-silicon tandem cells, and for its largest polysilicon processes. Restricted items include polysilicon plant engineering, wafer cutting and advanced cell processes. Finished panels are not covered. pv magazine notes that restricted technology can leave China only with government approval and licences, and warns of delays and higher costs for overseas factories.</p>

<p>China accounts for more than 80 per cent of global capacity at every stage of solar manufacturing, according to the trade outlet TaiyangNews. A Lowy Institute analysis last year found Southeast Asia has the largest module capacity outside China, about 106 gigawatts, with China supplying more than 80 per cent of foreign investment in new projects.</p>

<p>India is more exposed. Reuters reported in July that India has built about 200 gigawatts of panel capacity but can make only 27 gigawatts of cells, and relies on China for about 95 per cent of its cell imports. Industry sources told Reuters that Chinese curbs on equipment and technical support were already slowing new cell plants. Shanghai Metals Market frames the real question: can factories outside China, built on Chinese technology, keep upgrading?</p>

<p>The timing has context. Washington has spent years blocking China from the most advanced AI chips and chipmaking tools. Lian Jye Su of Omdia told AP the move can be seen as a response to Western sovereignty requirements on key technologies. Gary Ng of Natixis said the world is fragmenting not only in trade, but in access to technology. Beijing and Washington set up an AI incident channel last month, and AFP notes that several South Korean banks reportedly suffered cyberattacks last month involving a Chinese AI security tool.</p>

<h2>The Unfiltered verdict</h2>

<p>Beijing is now playing by rules Washington wrote. And the draft is narrower than it looks: APIs stay open, finished panels keep shipping, and open-source is exempt. But the target is clear. This is a leash on know-how, not a ban on products.</p>

<p>Asia can keep buying Chinese panels and AI services. What gets harder is learning to make them. For India's cell plants and Southeast Asia's China-plus-one factories, the lesson is the same: technology you rent can be recalled. The answer is not panic. It is homegrown engineering and regional deals that build skills, not just assembly lines.</p>

<p>What to watch: the final list after 15 November, how strictly registration is enforced, and whether overseas solar plants slip their schedules. Is China guarding its security, or locking in its lead?</p>
