China Gates the AI and Solar Tech Other Countries Use

China on Oct. 16 proposed new curbs on tech exports covering 40 items in AI, solar and biomedicine, and required companies to register transfers that day. The Ministry of Commerce and the Ministry of Science and Technology opened comments through Nov. 15 on the Catalogue of Technologies Prohibited and Restricted from Export.

The United States already limits chip tools bound for China. This draft aims at a different flow: the model weights, training methods and factory recipes that firms outside China have been taking out.

Forty Technologies Join a Catalog First Issued in 2001

Announcement No. 48 is a proposal, not a finished law. It would add 40 technologies in three fields: 23 in artificial intelligence, 12 in photovoltaics and 5 in biomedicine. Of those, 14 would be banned outright and 26 would need an export license. A commerce ministry spokesperson said the revision is routine catalog work under the Foreign Trade Law and “does not target any specific country, region or entity.”

The ministries’ draft catalog of Oct. 16 still bites before the comment window closes. From that date until a final revision takes effect, anyone exporting a listed technology must log the deal on the ministry’s technical-trade platform, including shipments already under way.

HOW THE 40 TECHNOLOGIES BREAK DOWN

Goods made with these processes sit outside the catalog. A solar panel, a finished chip or a drug can still leave. The know-how and, in some solar cases, the equipment that carries it cannot move as freely.

Lian Jye Su, chief analyst at the research firm Omdia, called the package a response to Western sovereignty rules on AI, robotics and telecoms. Gary Ng, a senior economist at Natixis, said access to technology is fragmenting along with trade and investment. Both read the geopolitics. The thresholds in the draft point somewhere more specific: at the next Chinese model that has not yet been posted, and at the engineering package for a large polysilicon line.

What the 2-Trillion-Parameter Line Catches

On the restricted list sit large models whose core technology includes weights, key checkpoints, underlying source code, architecture, training tricks and inference speed-ups. A model can trip the line if its training compute is at least 10^26 floating-point operations, if it has 2 trillion parameters or more, or if its capabilities are judged world-leading. The draft names no product.

Two Chinese systems already sit above that parameter mark. Moonshot AI’s Kimi K3 is a 2.8 trillion-parameter mixture-of-experts model whose weights went onto Hugging Face on July 27. Alibaba’s Qwen 3.8-Max, generally available from Aug. 3, is listed at 2.4 trillion parameters, with an open-weight twin in the same class. Both would be in scope for a new transfer of core technology. Weights that are already public are a different case.

A harder split sits in the data rules. Models trained on China’s “core data” and then offered as a service are proposed for a ban. Models trained on “important data” would need a license. Those labels come from the Data Security Law and shift by sector, which is why labs will spend the comment period asking where the line is.

The Chinese government is implementing such necessary measures with the aims of reinforcing the security bottom line, preventing misuse and abuse, and ensuring that AI remains under human control.

Banned AI items also include autonomous malicious-code generation and mutation, the kind of tool that can be pointed at networks, defense systems or government services. Restricted items include AI-assisted vulnerability discovery, voiceprint recognition, design technology for some AI processing chips and memory chips, including 2.5D and 3D packaging, and 3D flash. Compute-cluster know-how, from chip-to-chip interconnects to distributed training, is in the AI bundle too.

Open Weights Already Public Stay Public

The first public reading treated the draft as the end of Chinese open models. That is not what the notice says. Technology already in the public domain through open source or academic papers is carved out of the catalog. For future AI exports, the ministries list open-sourcing, a Chinese firm’s own overseas compute center, overseas chip tape-out, joint research that uses foreign resources, and work on international standards as cases that would get automatic licensing for open-source cases, described as report-and-go.

How a model “goes overseas” is the practical cut. After a final catalog is in force, parking a restricted model on someone else’s overseas servers is a technology export. Putting it on a Chinese firm’s own cloud abroad can use the fast license. API calls, apps, web chat, SaaS and a light on-device build are not treated as large-model technology exports. Most users who hit Qwen or Kimi through a webpage would not need a license. A lab that wants a US cloud to host the weights would.

Martin Chorzempa, a senior fellow at the Peterson Institute for International Economics, wrote that open models can still flow for now, and that officials “now have the system in place to throttle future release of open models if they choose.” The comment file will decide what an automatic license actually requires: a form, a safety report, a wait, or a quiet no. Until that is written down, a future Kimi or Qwen-class drop is a filing, not a git push.

Teams that fine-tune those stacks already treat a delayed checkpoint as an operations problem. A second vendor on standby, and a local copy of the weights they run today, is the dull version of that filing. The catalog does not pull Kimi K3 off a disk that already has it. It sits in front of whatever comes next.

A 30,000-Ton Line Is the Solar Gate

Twelve photovoltaic items cover polysilicon, wafers and cells, plus some of the equipment that carries those processes. Perovskite and tandem module production is proposed for a ban. The license example that will matter to anyone building a plant outside China is polysilicon engineering for a single line of 30,000 tons a year or more.

CHINA’S HOLD ON THE SILICON

• 2025 output share: The China Photovoltaic Industry Association put China’s polysilicon output at 1.367 million tons, 92.1% of the world total of 1.485 million tons.
• Plants running: Sixteen producers were in operation, at an average 39.3% operating rate, after a glut that cut output by 25.0% from the year before.
• Who makes it: The world’s seven largest producers by output were all in China, together 82.1% of global volume.
• The license size: A single polysilicon line of 30,000 tons a year or more needs a license; Morocco in late 2025 announced a 30,000-ton project, and an Oman venture has a 100,000-ton design.

That 92.1% figure is last year’s output. Across manufacturing stages, the International Energy Agency still puts China at more than 80 percent of solar manufacturing capacity for polysilicon, wafers, cells and modules. Those are different slices of the same pile. The catalog does not stop panel shipments. It reaches the recipe, the install crew and the upgrade that turn a foreign site into a Chinese-designed line. Operators who export, install, debug or upgrade a controlled process are told to apply for a license and then clear foreign exchange, tax and customs against it.

On Oct. 11, eight firms that hold more than 80% of China’s effective polysilicon capacity met in Hangzhou on price floors and output cuts. They are sitting on idle plants at home and, five days later, on a draft that would make it harder to sell the large-line package abroad. Smaller processes that miss the numeric cuts can still go out. Unlisted solar equipment, the ministries said, is generally outside this notice.

Cell Therapy Platforms and Chip Designs Join In

Biomedicine adds five items around pathogens, cell and gene therapy, and small nucleic-acid drugs. Proprietary cell and gene therapy process platforms are in the ban examples. New target discovery and validation would be licensed. Pathogen-related technology is framed as a biosafety ban, not a trade tactic.

The bio rules have their own exits. Outbound licenses that do not transfer ownership can use automatic licensing. Using a proprietary process platform to license a partner or to run contract research and manufacturing is described as out of scope. Public-health emergencies, humanitarian work and joint research that uses foreign labs also get the fast track. The ministry is trying to keep CDMO work and trial partnerships moving while locking the platform itself.

Chip entries sit inside the AI block rather than as a separate solar-style list. Design technology for some AI processors and memory, including 2.5D and 3D packaging, and 3D flash would need licenses. That is a thinner cut than a full tool ban, and it still lands on packaging know-how that Chinese foundries and designers have been selling as a service.

Exporters Must Register Before the Catalog Is Law

The comment email is jinxianmulu@mofcom.gov.cn. The legal change that is already in force is the registry. From Oct. 16 until a final catalog is issued, an exporter must file before a listed technology leaves, on the ministry platform at ecomp.mofcom.gov.cn. Deals that started earlier and are not finished are in the net.

WHAT COUNTS AS AN EXPORT FOR THE REGISTRY

• Ownership transfer: Assigning intellectual property to a party outside China.
• A license to use: Authorizing an overseas firm to use the technology.
• A change of control: The owner or actual controller becoming a foreign person or company.
• Other notices: Any further case the commerce ministry flags in writing.

Filers give buyer and seller names, destination, the technology and its use, and an expected value. Several items going to one recipient can share a form. The spokesperson said the interim step is to see what demand looks like and to limit risk while comments run. It is also a list of who has been sending what, before any license exists.

WHAT WE KNOW

• The draft: Forty additions, 14 bans and 26 licenses, published Oct. 16 with comments through Nov. 15.
• The live rule: Pre-export registration already covers the listed technologies, including unfinished transfers.
• The carve-outs: Already-public open source and papers are out of scope; APIs, apps and SaaS are not treated as large-model exports.

WHAT IS UNCONFIRMED

• Final cuts: Whether the 2-trillion-parameter line, the 10^26 compute line or the 30,000-ton solar line moves after comments.
• Automatic licenses: What paperwork, safety terms or timing will attach to the report-and-go path.
• Named models: The draft lists no Kimi, Qwen or DeepSeek product; those names are the market reading the parameter line.

The ministries say they took industry comments before publishing, that most listed items have numeric tests, and that they will drop technology that is no longer advanced. They have said that before. The December 2023 edition of the catalog ran to 134 entries, 24 of them bans and 110 licenses. A later update, the July 2025 battery-process additions translated by Georgetown’s Center for Security and Emerging Technology, put cathode materials and lithium extraction on the restricted list and took traditional building methods off. The catalog has been opened and closed since 2001. This round is larger, and it is the first to put frontier-model weights in the same drawer as a polysilicon line.

November AI Talks Will Meet a Live Registry

HOW THE EXPORT CATALOG HAS CHANGED

1. 2001: The commerce and science ministries begin issuing a catalog of technologies banned or limited for export, under the Foreign Trade Law.
2. December 2023: A revision leaves 134 entries, 24 of them bans and 110 licenses, after dozens of deletions and a handful of additions.
3. July 15, 2025: Battery cathode processes and lithium-extraction methods are added; traditional Chinese building technology is removed.
4. Sept. 24-25, 2026: Xi Jinping and Donald Trump agree to keep a China-US AI dialogue and to set up a channel for AI incidents that raise national-security alarms.
5. Oct. 16, 2026: Announcement No. 48 proposes 40 AI, solar and biomedicine additions and turns on pre-export registration the same day.
6. Nov. 15, 2026: The public-comment window on the new items closes; a November AI dialogue is already on the calendar.

The safety talks and the catalog are not a contradiction on paper. Beijing’s own briefing says the aim is to keep AI under human control and to stop misuse, the same language used around the incident channel. The operational fact is cruder. By the time the two sides sit down in November, Chinese exporters of listed technology will already have been filing names, destinations and values for a month.

Members of a China-backed World AI Cooperation Organization are promised extra help on capacity-building exports. Global South labs that want Chinese models are being told, in the same breath, that the door is open and that the door has a clerk. The clerk’s stamp is the part of this draft that is not waiting on November.
