China proposes export curbs on 40 AI, solar and biomedicine technologies
In one line: China has proposed to ban the export of 14 technologies and license 26 more in AI, solar power and biomedicine, which could slow India's plan to make more of its solar supply chain at home.
Published 17 October 2026. Written by Pratidin from the reports linked at the end; every fact checked by a separate review before publishing. How we work
On 16 October 2026 China's Ministry of Commerce (MOFCOM) and Ministry of Science and Technology issued Announcement No. 48 of 2026. It is a draft revision of the Catalogue of Technologies Prohibited or Restricted from Export, the list that decides which Chinese know-how may leave the country. The draft adds 40 technologies: 23 in artificial intelligence, 12 in photovoltaics (solar power) and 5 in biomedicine. Of these, 14 would be prohibited outright and 26 would be restricted, meaning their export would need a licence. Public comments are invited from 16 October to 15 November 2026.
The prohibited list includes certain perovskite and tandem solar cell and module manufacturing technologies, AI-driven malicious code technology and some cell and gene therapy platforms. The restricted list includes polysilicon engineering technology for production lines with an annual capacity of 30,000 tonnes or more, along with technologies for wafers and cells. Technologies already public through open-source releases or academic papers would generally be exempt, and The Hindu reported that most AI technologies would remain freely exportable. Until the revised catalogue takes effect, companies must register planned technology exports with MOFCOM, a rule that applied from 16 October 2026 and also covers deals already under way.
China says the move is routine. The catalogue was first published in 2001 and revised in 2008, 2020, 2023 and 2025, and a MOFCOM spokesperson said the revision 'does not target any specific country or region'. The Hindu noted that the controls on next-generation solar technology could affect efforts by countries including India to reduce dependence on China as they move up the solar chain. India's ₹24,000 crore Production Linked Incentive scheme for high-efficiency solar modules aims to build integrated factories that make more of that chain at home.

Recurring theme: Supply-chain dependence on China and India's push for technology self-reliance
- How to use this
Show that diversifying away from China is constrained when China controls the know-how, using its October 2026 export curbs on solar and AI technologies.
- China's October 2026 draft would prohibit 14 and restrict 26 AI, solar and biomedicine technologies, including large polysilicon lines.
- India's ₹24,000 crore solar PLI favours integrated plants that need exactly this upstream know-how.
- Building alternatives therefore needs technology partnerships, not just factories.
- How to use this
Use China's proposed technology export curbs as a current example of the turn towards protectionism and what it means for India's manufacturing ambitions.
- China proposes licences or bans for 40 technologies, with a pre-export registration rule applying from 16 October 2026.
- Next-generation perovskite and tandem cell technology would be barred from export.
- Response: domestic R&D, diversified partners and integrated PLI-backed plants.

Mains practice question
China's proposed curbs on exporting advanced solar and AI technologies show that technology is now a tool of statecraft. Examine the implications for India's ambition to build a domestic solar manufacturing chain. (150 words)
Model answer
On 16 October 2026 China proposed adding 40 AI, solar and biomedicine technologies to its export control catalogue: 14 to be prohibited and 26 restricted.
Technology as statecraft
- Controls now cover know-how, not just goods: licences, designs and processes.
- The draft targets areas of Chinese strength: perovskite and tandem cell manufacturing (prohibited) and large polysilicon lines of 30,000 tonnes a year or more (restricted).
- A pre-export registration rule from 16 October 2026 gives Beijing visibility of deals in progress.
Implications for India
- India's ₹24,000 crore PLI scheme favours integrated plants; Tranche I awarded 8,737 MW of fully integrated capacity.
- Upstream stages (polysilicon, wafers, cells) need process technology that may now require Chinese approval.
- Next-generation cells could stay out of reach, widening the efficiency gap.
Way forward
- Fund domestic research in perovskite and tandem cells.
- Diversify technology partners for upstream stages.
- Use the comment window to the extent trade diplomacy allows.
Supply-chain resilience in solar needs home-grown know-how, not only subsidised assembly.
The basics
Why this matters
Export controls are no longer only about weapons. On 16 October 2026 China proposed to stop or license the export of 40 technologies in artificial intelligence, solar power and biomedicine. India is trying to build its own solar supply chain, so the move touches its industrial plans directly.
What a technology export control is
A country can control the export of goods and also of technology: designs, processes, licences and know-how (Technology export controls). China does this through a list called the Catalogue of Technologies Prohibited or Restricted from Export. It rests on the Foreign Trade Law and the Regulations on the Administration of Technology Import and Export. A prohibited item cannot be exported at all. A restricted item can be exported only with a licence.
- Cannot be exported
- Includes perovskite and tandem solar cell and module manufacturing
- Includes AI-driven malicious code technology
- Export needs a licence
- Includes polysilicon engineering for lines of 30,000 tonnes a year or more
- Most AI technologies stay freely exportable
The proposal in numbers
Technologies already public through open-source releases or academic papers are excluded. Until the revised catalogue takes effect, exporters must register planned technology exports with the Ministry of Commerce (MOFCOM). Public comments are open from 16 October to 15 November 2026.
The solar chain, step by step
Each stage of a silicon panel needs its own know-how and equipment, so controls on technology, not just products, matter. See Solar PV value chain and Perovskite and tandem solar cells.
- 1PolysiliconPurified silicon, made in large plants; China proposes to restrict know-how for lines of 30,000 tonnes a year or more
- 2Ingot and waferSilicon is grown into crystals and sliced into thin wafers
- 3CellWafers are processed into cells that turn light into electricity
- 4ModuleCells are wired, framed and sealed into the panel sold to developers
India's stake
India's PLI scheme for solar modules has a total outlay of ₹24,000 crore and favours integrated plants that make more of the chain at home. The Hindu's report noted that the new controls on next-generation solar technology could hit efforts by countries including India to reduce dependence on China and move up the solar chain.

Why it matters for UPSC
The story links GS2 (effect of other countries' policies on India's interests) with GS3 (indigenisation of technology, energy and industrial policy). It is also a Prelims hook on solar technology terms such as polysilicon, wafers, perovskite and tandem cells.
The core idea
Countries guard their lead in strategic sectors through Technology export controls. China's catalogue has two tiers: prohibited and restricted. The new draft goes after the most advanced parts of the Solar PV value chain, including next-generation Perovskite and tandem solar cells, and large polysilicon plants. India is using the PLI scheme for solar modules to build integrated factories, which need process know-how for every stage.
Numbers and dates to remember

Where to go next
- Technology export controls: why states restrict know-how, not just goods.

Go deeper: routine housekeeping or strategic lever?
China's case: a MOFCOM spokesperson said the catalogue has been adjusted many times since 2001 and that the revision is routine, 'does not target any specific country or region' and aims to make exports more transparent and predictable. Chinese experts quoted by the Global Times argued that the US, EU, Japan, the UK and South Korea also manage technology exports regularly. A solar industry executive quoted by the paper said mature manufacturing technologies and equipment are not barred.
The critics' case: the draft targets exactly the technologies where Chinese firms lead, such as perovskite cells, and the stages where other countries are trying to catch up, such as large polysilicon plants. Under Technology export controls, a licence requirement gives the state discretion over who gets know-how, and when. A new pre-export registration rule, applying from 16 October 2026, also gives Beijing early visibility of deals in progress.
What it means for India: India's PLI scheme for solar modules awarded 8,737 MW of fully integrated capacity in Tranche I and 39,600 MW of fully or partially integrated capacity in Tranche II. Integrated plants need process know-how for each step of the Solar PV value chain. If the know-how for upstream steps or for Perovskite and tandem solar cells needs a Chinese licence, Indian manufacturers may face delays or must seek other partners.
The wider pattern: technology is becoming a tool of statecraft. The United States restricts advanced chip exports to China, and China now uses its own catalogue in sectors where it leads. For India, the lesson is to invest in domestic research and diversify technology partners, rather than rely on one source for a strategic sector.
Technology export controls
Why states restrict know-how, not just goods.
In one line: Technology export controls let a state stop or license the transfer of know-how, not just the sale of goods.
What they cover
A technology export is not only shipping a machine. It includes selling or licensing a patent, a design, a production process or the right to use know-how abroad. China's rules cover transfers of technology ownership to foreign entities, licensing domestic technology for use abroad, and changes that make a foreign entity the owner or controller.
How China's system works
China keeps a Catalogue of Technologies Prohibited or Restricted from Export under its Foreign Trade Law and the Regulations on the Administration of Technology Import and Export. Prohibited items cannot be exported. Restricted items need a licence. The 2026 draft also excludes technology already public through open-source releases or academic papers, and allows easier, automatic licensing in some listed cases.
Why it is in the news
On 16 October 2026 China proposed adding 40 technologies, 14 prohibited and 26 restricted.
Where to go next
Solar PV value chain
The stages from polysilicon to module.
In one line: A crystalline silicon solar panel is made in four broad stages, and each stage needs its own technology and machines.
The stages
Polysilicon is highly purified silicon made in large chemical plants. It is melted and grown into crystals called ingots, which are sliced into thin wafers. Wafers are processed into cells, which turn sunlight into electricity. Cells are wired together, framed and sealed into modules, the panels that developers buy.
Why upstream is hard
Module assembly is the easiest stage to set up. The upstream stages, polysilicon, ingots and wafers, need costly plants and process know-how. That is why policies that reward integrated plants try to pull these stages into the country.
Why it is in the news
China's October 2026 draft would restrict polysilicon engineering technology for lines of 30,000 tonnes a year or more, along with technologies for wafers and cells.
Where to go next
Perovskite and tandem solar cells
The next-generation technology China wants to keep.
In one line: Perovskite and tandem cells are next-generation solar technologies, and China wants to bar their manufacturing know-how from export.
What they are
Most panels today use crystalline silicon cells. A perovskite is a class of crystal material that can also absorb light and turn it into electricity. A tandem cell stacks two layers, for example a perovskite layer on top of a silicon cell, so that each layer captures a different part of sunlight. This can raise the share of sunlight converted into power.
Why it matters
The technology that raises efficiency decides who leads the next round of solar manufacturing. The Global Times said perovskite technology could significantly raise cell efficiency and that Chinese firms hold a global lead.
Why it is in the news
China's draft puts certain perovskite and perovskite-tandem cell and module production technologies in the prohibited tier.
Where to go next
PLI scheme for solar modules
India's ₹24,000 crore push for home-made panels.
In one line: India's Production Linked Incentive (PLI) scheme for high-efficiency solar PV modules pays makers for output to build gigawatt-scale factories at home.
How it works
The National Programme on High Efficiency Solar PV Modules has a total outlay of ₹24,000 crore. Incentives are paid for five years after a plant is commissioned, on the manufacture and sale of high-efficiency modules. A stated aim is to set up integrated plants for better quality control and competitiveness.
Two tranches
Tranche I (₹4,500 crore) was approved by the Cabinet on 7 April 2021 and run by IREDA; it awarded 8,737 MW of fully integrated capacity. Tranche II (₹19,500 crore) was approved on 21 September 2022 and run by SECI; in April 2023 it awarded 39,600 MW of fully or partially integrated capacity to 11 bidders.
Why it is in the news
Integrated plants need upstream know-how that China now proposes to restrict.
