China Plans to Ban or Restrict Exports of AI and Solar PV Technologies

China's Commerce and Science ministries opened a public consultation on export controls covering 40 technologies across AI, biopharma, and solar manufacturing, with comments due November 15 — this means Beijing is extending its tech-export toolkit from chip retaliation to the upstream know-how that built its industrial lead.
What does this draft actually control?
The draft designates 14 technologies as outright export bans and 26 more as requiring a licence before export.
Scope: 23 AI technologies, 5 biopharma technologies, 12 solar technologies — precisely the three fields where China holds its strongest global competitive edge.
This means → the target is not finished products but the underlying process know-how used to make them. Selling the product is fine; selling "how to build it" is not.
How strict are the AI controls? What's exempted?
The core test: whether restricted tech transfers from China to a foreign recipient. Deploying it for your own use does not count as an export.
Companies running restricted AI tech on their own overseas cloud platforms can apply for automatic licensing. Access provided via API, app, website, or SaaS — software as a service, delivering software on-demand over the cloud — falls outside the large-model export controls.
Tech already released through open-source publication or academic papers is also excluded. In plain terms = the rule targets "packaging core tech and handing it to a foreign party," not shutting down every cross-border AI operation.
Why do the solar controls deserve a closer look?
Solar controls go beyond know-how itself, extending to specific equipment that embodies the restricted technology. This means → Beijing is not just banning "teaching you how to build it" — it may also block "the machines that build it for you."
Technologies slated for a full ban include perovskite and tandem solar-cell tech — the leading next-generation high-efficiency battery designs — and some thin-wafer processes. Advanced TOPCon, HJT, and XBC manufacturing tech faces restrictions short of an outright ban.
Reuters reported that Chinese authorities had already discussed controls that could affect U.S. production plans, involving companies such as Tesla, while also considering curbs on transferring solar manufacturing tech to India.
How does the transition work? What about deals already under way?
From October 16 until the revised catalogue takes effect, all relevant transactions must undergo provisional registration — including deals that have started but not yet closed.
Reportable transactions include: transferring technology ownership abroad, licensing foreign parties to use Chinese tech, and any change that shifts ownership or effective control of Chinese technology to a foreign entity.
In plain terms = the draft is not yet law, but from the day the consultation opened, deals in progress must be filed first — "freeze first, set the rules later."
What does this signal in the bigger picture?
The Commerce Ministry characterised the revision as "routine management," stressing it does not target any specific country, region, or entity. Products made using the listed technologies are not covered.
Natixis senior economist Gary Ng told the Associated Press that AI is becoming increasingly strategic for both Washington and Beijing: "The world is fragmenting in trade and investment, and also in access to technology."
This reflects a shift from "who will sell me chips" to "I won't sell you the process." China is moving from absorbing export controls to wielding the same tool. Whether the controls land on schedule — and whether the final scope narrows — will be the key marker for China's tech-export policy direction.
