Why is China restricting exports of its key technologies?

In one week in October, China proposed export limits on 40 technologies and added tunnel boring machines and more drones to its control lists. The items range from AI models to solar factory know-how to giant drills, which makes the pattern hard to read from any one story.

THE SHORT ANSWER

Because China says national security requires it, and because export licensing has become one of its main answers to US technology limits. The commerce ministry called the October draft "necessary" and cited security. It also named preventing misuse of AI as an aim. The reports so far do not say why these particular items were chosen. The curbs arrive after years of US restrictions on advanced chips and chipmaking machines, and after tit-for-tat steps on drones in August.

What happened

On Friday 16 October, China's Commerce Ministry and Ministry of Science and Technology published a draft revision of the catalogue of technologies that are banned or restricted from export. It adds 40 technologies: 23 in artificial intelligence, 12 in solar power, five in biomedicine (including cell and gene therapy) and several chip design technologies. Fourteen would be banned outright and 26 restricted. Public comment runs to 15 November. A temporary requirement to register before exporting any listed technology took effect the same day.

The AI items include core technologies of large models trained on sensitive national data, which would be prohibited, and AI agents built for settings such as national defence and critical information infrastructure. Models with 2 trillion parameters or more, or with certain world-leading capabilities, could be restricted. Parameter count is a rough measure of a model's learning capacity. The solar items cover polysilicon, wafer and cell manufacturing, plus some core equipment.

On Monday 19 October, the Commerce Ministry announced a second set of measures, due to take effect on 18 November. Tunnel boring machines, rock borers and some dredger parts come under export control, and the reports say tunnel borers had not been controlled before. Revised drone rules require licences for drones that fly beyond the operator's line of sight, and for certain engines, propellers and flight-control software, including swarm control. Some qualifying drone exports get a simpler registration route.

Why it matters

China is a leading supplier in several of these fields, so its licensing decisions reach factories, tunnel builders and AI developers far outside its borders. The two announcements also show export controls being used on both frontier technology and heavy industrial equipment. They land while the US and China are negotiating over AI, tariffs and rare earths, so each side's technology limits may feed into those talks.

  • For solar manufacturers outside China, The rules target technology transfers and specified equipment, not finished panels. Plants built on Chinese lines may find it harder to ramp up or upgrade on schedule if technical support slows.
  • For infrastructure contractors, Firms that buy Chinese tunnel boring machines may face delays or look for other suppliers while licences are reviewed.
  • For drone makers and buyers, High-end models need licences from 18 November. Qualifying drones can use simplified registration, which may keep consumer and commercial trade moving.
  • For AI developers, Some model technologies would be banned or restricted, and the draft does not name specific models. Several Chinese models are reported to be above the 2 trillion parameter mark.

The background: a technology contest and a new legal toolkit

Scattered rules, then one law

Since the 1990s, China has issued six separate administrative regulations on export control, covering areas such as controlled chemicals, nuclear items, military products, missiles and biological dual-use items. A dual-use item has both civilian and military uses. The material available says the lack of one unified law made enforcement hard to coordinate, and that the United States and the European Union already had unified export control laws.

China also keeps a catalogue of technologies that are banned or restricted from export. It has revised that catalogue repeatedly since 2001, adding and removing technologies, under a foreign trade law that lets the commerce ministry set the list.

The Ministry of Commerce began drafting a single Export Control Law in 2017 and published a draft for comment on 16 June 2017. The national legislature passed the law on 17 October 2020, and it took effect on 1 December 2020. It sets up a licensing system: exporters need a licence for any listed or temporarily controlled item. It covers goods, technologies and services tied to national security and to duties such as non-proliferation. It also lets China take reciprocal measures against any country that abuses export controls in a way that endangers Chinese security and interests.

An industrial plan and a trade war

In May 2015, Premier Li Keqiang signed Made in China 2025, a national plan to move Chinese manufacturing away from cheap, low-tech goods and toward higher-value production. Its target industries include aerospace, biotech, robotics and new materials. The plan set targets for domestic content in core materials. In October 2024, Bloomberg research called the plan largely a success. It counted China as a global leader in five of 13 tracked technologies, including drones and solar panels.

A US-China trade conflict began in January 2018, when President Donald Trump started imposing tariffs and other trade barriers on China. The US said it was responding to unfair trade practices and intellectual property theft. On 15 June 2018, the US raised tariffs on Chinese goods, mainly manufactured goods covered by Made in China 2025. The Chinese government argues that the real US goal is to stifle China's growth.

Technology limits on both sides

Washington and its partners have curbed technology sales to China. US-led restrictions have blocked China from the most advanced AI chips and the machines that make them. On 27 January 2023, the EU's internal market commissioner announced that the EU would join the US in blocking sales of technology that lets China make advanced chips. On 17 February 2023, China expanded its Unreliable Entities List to include Raytheon and Lockheed Martin.

Tariffs also targeted China's strongest industries. On 14 May 2024, the Biden administration doubled tariffs on solar cells imported from China. On 9 June 2026, the US added Alibaba, Baidu and BYD to its list of Chinese military companies. Reports this month describe export controls as one of Beijing's main tools for answering US restrictions on Chinese firms' access to advanced technology. A report published this year by the EU Chamber of Commerce in China warned that Beijing increasingly uses them as a pressure instrument.

Summer 2026: AI and drones

On 5 August, Implica reported that China was weighing a tiered regime that could restrict downloads of its frontier AI model weights while keeping cloud access open. Two days later, we reported that Washington was restricting foreign access to models such as Anthropic's Mythos, so both countries were moving to wall off top AI systems.

On 8 August, China sanctioned six US firms and curbed drone exports. The reports describe this as a response to US drone import bans from the Federal Communications Commission and to forced-labour sanctions on Chinese firms in Xinjiang. On 13 August, Trump imposed tariffs of up to 100% on imported drones. On 15 September, China's new border rules took effect, letting it bar citizens deemed technology-security risks, and Taiwan told its tech workers to think twice about visiting. On 20 September, US and Chinese negotiators opened talks in New York on AI, tariffs and rare earths, trying to preserve a trade truce due to expire on 10 November.

The October drone rules came two and a half months after Beijing tightened drone export controls toward the US.

This month: the catalogue and the machines

The 16 October draft is the widest of the recent steps. The commerce ministry said it was "reinforcing the security bottom line, preventing misuse and abuse, and ensuring that AI remains under human control". It came as the US and China reported progress in talks on AI safety and on a mechanism to notify each other of AI incidents that could threaten national security.

On 19 October, the ministry said tunnel boring machines and dredger parts have an "obvious military-civil dual-use nature". It said the measures follow common international practice and better meet non-proliferation duties. On drones, it said some once-advanced products are now ordinary consumer goods. It also said China opposes drones being misused for non-peaceful ends while backing civilian drone trade.

GOOD TO KNOW

Tunnel boring machines are the giant drills that dig subway, road and water tunnels. China's manufacturers are the world's largest suppliers, and this is the first time some types have been put under export control.

What does pre-export registration change?

Registration is separate from the draft catalogue. Reports say it applies from 16 October until the revised catalogue takes effect, and covers listed technology exports that have started but are not finished. It does not by itself authorise an export. Whether a technology is finally banned or restricted, and which thresholds apply, depends on the final catalogue.

The 15 November date is the end of public comment, not a confirmed start date for the final list. The draft should not be read as the final list. Technologies below the control thresholds, and unlisted solar equipment, are not automatically restricted.

Why does dual-use matter?

Dual-use means an item can serve civilian and military purposes. China's ministry used that label for tunnel borers and dredger parts. Drones are the clearest case: the military and police work behind them is the reason given for tighter rules, even though many are sold as consumer products. The reports say China is the leading supplier of civilian drones, with DJI the global leader.
