research topics.

Three firms — Alibaba (33%), Huawei (18%), Tencent (10%) — hold ~61% of China’s cloud market. AI has reignited it: Alibaba Cloud grew 26% last quarter, backed by a $53bn build-out.

Huawei’s CloudMatrix 384 wires 384 Ascend chips into a system that beats Nvidia’s GB200 NVL72 on total compute — using 5x the chips and 4x the power. China’s answer to being cut off from Nvidia: brute force.

Alibaba Cloud is opening data centres in eight new locations — its first in Brazil, France and the Netherlands — adding to 91 zones across 29 regions, and carrying its Qwen AI models abroad as the wedge.

OceanBase, built inside Alibaba, set the TPC-C database world record (707 million tpmC), breaking a mark Oracle held for nine years. Behind it, a national ‘xinchuang’ push is replacing foreign databases wholesale.

WeChat has 1.4 billion+ users and hosts 4.3 million mini-apps that moved ~8 trillion yuan in 2024. With Alipay it handles ~96% of Chinese mobile payments. The ‘everything app’ the West keeps trying to build.

China leads in consumer apps and databases — but its enterprise SaaS market is tiny and unprofitable. Its whole industrial-software market (~$50bn) is smaller than SAP alone, and leaders like Yonyou run ~30% cloud vs Autodesk’s 90%.

Alibaba’s Qwen is the world’s most-downloaded open AI model — 2bn+ downloads, 150,000+ derivative models, more than Meta and Google combined. Giving the models away is the strategy, not charity.

China’s ‘East Data, West Compute’ plan routes computing from the data-hungry east to the renewable-rich west: 8 national hubs, 10 clusters, ~¥200bn+ invested, 1.95m+ server racks. State planning, applied to compute.

Alibaba Cloud is ~36% of China’s market but only ~4% of the world’s — a seventh of AWS’s 30%. It runs thinner margins, is largely shut out of the West, and still trains on Nvidia’s export-throttled chips. Huge at home, small abroad.

Smart-glasses shipments grew 139% in H2 2025. Meta leads at 82%, but Xiaomi is #2 globally, Chinese brands own the AR niche, and Goertek of Shenzhen builds Meta’s Ray-Bans. The category’s centre of gravity is split.

DJI holds ~70-80% of the world’s consumer drones and half of US commercial ones. It sits on the US Entity List (2020), a Pentagon ‘military company’ list (2022, upheld 2025) and the FCC Covered List (2025) — and still dominates.

China is now the world’s largest wrist-worn device market — up ~20% while the global market shrank — and Huawei took the global #1 wearables spot from Apple in 2025, with Xiaomi close behind.

Roborock is the world’s #1 robot-vacuum brand, and four of the global top five are Chinese — the only US name, iRobot, is shrinking. The same firms are now taking robotic lawn mowers and pool cleaners global.

Quectel is the world’s #1 cellular IoT module maker; China holds ~54% of the global market. These radios connect billions of devices — meters, cars, trackers — which is why US lawmakers want Quectel and Fibocom blacklisted.

Tuya is the white-label cloud behind millions of no-name smart devices — 1.3 million+ registered developers, now profitable. It’s the invisible OS of the connected home, and Xiaomi’s rival platform passed a billion devices.

Insta360 holds ~71% of the 360-camera market; with DJI it owns 87% of handheld cameras, leaving GoPro below 6%. Its 2025 Shanghai IPO surged 285% on day one to a ~$9.7bn valuation. Won on innovation, not price.

Xiaomi’s ecosystem connects 1.07 billion+ devices, its 2025 revenue hit RMB457bn (+25%), and its YU7 SUV drew 289,000 orders in an hour at a Model-Y-beating price. The budget brand went premium — and integrated.

China leads in smart devices and integration — but foreign firms still supply ~80% of smartphone processors and the flagship image sensors, all built on UK-owned Arm. And the West keeps closing its markets to Chinese hardware.

China has led the world in reactors under construction for 19 straight years — ~37 building now, ~64 operating — and approves 10+ a year. It is set to pass the US as the world’s largest nuclear operator by ~2030.

China builds reactors at ~$2,500/kW; the US Vogtle plant came in near $15,600/kW and Britain’s Hinkley Point C at ~£46bn. Serial designs, a domestic supply chain and 1.4% state loans break the cost curse.

China’s Hualong One is a ~90%-localised Gen-III reactor, proven at home and exported to Pakistan. But the UK ejected its co-developer CGN on security grounds, and the US Entity List shut the door. Strong at home, walled out abroad.

China’s HTR-PM is the first commercial Gen-IV pebble-bed reactor. In a 2024 test, engineers cut all cooling to both modules; the reactors stabilised on their own within ~36 hours. It is, in effect, meltdown-proof.

China’s Linglong One (ACP100), a 125 MWe small modular reactor on Hainan, is set to be the world’s first commercial land-based SMR in operation — targeting 2026, while America’s flagship SMR project was cancelled in 2023.

China’s TMSR-LF1 in the Gobi Desert is the world’s only operating thorium molten-salt reactor. It runs on abundant thorium, needs no water cooling, and in 2025 became the first to breed uranium fuel from thorium — reviving a US idea shelved in the 1970s.

China’s EAST tokamak held a plasma for 1,066 seconds, it outspends the US on fusion, and a startup built a tokamak in 2 years. The catch: none of it generates electricity, and commercial fusion is still a ~2050 prospect.

China is closing its nuclear fuel cycle: fast-breeder reactors (CFR-600) that make more fuel than they burn, new reprocessing plants, and a ‘thirds’ uranium strategy spanning mines from Namibia to Kazakhstan. Sovereignty — with proliferation questions attached.

China leads the world in reactor construction — yet nuclear is just ~5% of its electricity, coal still over half, and wind and solar each already out-supply it. The build is real; the energy-mix impact is still modest.

Roughly a third of Big Pharma’s in-licensed innovative pipeline now originates in China. Pfizer paid 3SBio $1.25bn upfront for one bispecific in 2025; total China-out deal value hit a record.

Insilico’s rentosertib — AI-picked target, AI-designed molecule — showed a lung-function benefit in a 71-patient Phase IIa and has entered Phase III. XtalPi has signed AI-discovery deals with Lilly and Pfizer.

China has ~1,006 registered CAR-T trials to the US’s 549 — the world’s most. Its cost-and-speed edge comes from a hospital-based pathway. But volume of trials is not the same as approved products.

China approved its own dual GLP-1 obesity drug (mazdutide) in 2025 and licensed Hengrui’s GLP-1s to a $400m US NewCo. When semaglutide’s China patent expires in March 2026, ~16 domestic copies are queued.

Foreign brands’ share of China’s high-value medical devices fell from ~80% to ~70% in a decade. United Imaging now builds 5-tesla MRIs and sells in 85+ countries; volume procurement cut some device prices 80-95%.

WuXi Biologics alone held ~10% of the global biologics-outsourcing market, serving every top-20 pharma. The US BIOSECURE Act became law in Dec 2025 — but the enacted text names no companies, deferring that to a future list.

MGI (a BGI offshoot) won $333m from Illumina in a US patent case, entered the American market, and sells genome sequencing for under $100. Its sequencer installs jumped ~49% in 2024 — even as BGI affiliates hit the US Entity List.

China approved NEO — billed as the first invasive brain-computer interface cleared beyond trials — in 2026. Its patients have regained hand movement; a rival device decoded 60+ Chinese words. Neuralink had 21 patients.

China’s first-in-class pipeline grew from 9 candidates (2015) to ~120 (2024), ~24% of the world’s. But critics note many ‘novel’ drugs are new formats on known targets — and a 2016 audit saw ~73% of trials withdrawn.

China went from ~a dozen space firms in 2015 to ~300 by 2022. Eight have reached orbit. In 2023 LandSpace beat SpaceX, ULA and Blue Origin to fly the world’s first methane-fuelled rocket to orbit.

In Aug 2026 LandSpace’s Zhuque-3 landed a booster on land — a Chinese first. But SpaceX first did this in 2015 and has 600+ landings since. Recovery is not yet reuse, and China has flown neither.

China’s two Starlink rivals — state-owned Guowang (~13,000 sats) and Shanghai’s Qianfan (>15,000) — plan ~28,000 satellites between them. By 2026 only a few hundred were in orbit. The bottleneck: rockets.

China’s satellite ‘super factories’ are rated to build 240 (CASIC Wuhan) and 500 (Geely) spacecraft a year, cutting build time from months to weeks. The catch: nameplate capacity runs far ahead of what actually ships.

In 2024 China launched 68 times; SpaceX 138 — and Falcon 9 alone lifted 84% of all satellite mass to orbit. China flew zero operationally reusable rockets. The ambition is real; so is the gap.

BeiDou — China’s answer to GPS — went global in 2020 with ~30 core satellites. It’s in ~94% of smartphones sold in China, used across 200+ countries, and anchors a ~400bn-yuan navigation economy.

China completed its 3-module Tiangong station in 2022 and aims to land astronauts on the Moon before 2030, with a new rocket, crew capsule and lander. NASA’s Artemis landing has slipped toward 2028 — it’s a real race.

Chang’e-6 returned the first-ever samples from the Moon’s far side in June 2024. With an asteroid mission under way and a Mars sample-return planned for ~2028, China may beat NASA and ESA to Martian soil.

In May 2025 China launched the first 12 satellites of a planned 2,800-strong ‘Three-Body Computing Constellation’ — an orbital AI supercomputer targeting 1,000 peta-operations/sec, built to process data in space, not beam it down.

China holds >80% of every stage of the solar supply chain and ~95% of the world’s wafers. One province, Xinjiang, makes ~40% of global polysilicon. It is the most concentrated supply chain in modern industry.

CATL (37.9%) and BYD (17.2%) alone made 55% of the world’s EV batteries in 2024; all Chinese firms together ~65%. Chinese packs cost $84/kWh — against $121 in North America and $131 in Europe.

China passed Japan as the world’s top car exporter in 2023 (4.91M vs 4.42M) and shipped 5.86M in 2024. Now come EU tariffs up to ~35%, a US 100% duty — and Chinese plants in Hungary, Thailand and Brazil.

CATL’s chairman puts solid-state battery maturity at ‘level four of nine’ and mass production ‘not before 2030.’ Beijing has put >6 billion yuan behind it — but today’s ‘semi-solid’ cells are not the real thing.

CATL’s Naxtra sodium-ion cell hits 175 Wh/kg, keeps 90% of its power at −40°C and lasts >10,000 cycles. The catch: lithium is ~70% below its 2022 peak, so sodium doesn’t yet undercut LFP on cost.

China deployed 65 GWh of grid batteries in December 2025 alone — more than the US installed all year. Then ‘Document 136’ scrapped the mandate forcing the build, because much of it was sitting idle.

China added 68% of the world’s new wind capacity in 2024, and for the first time the top four turbine makers — Goldwind, Envision, Mingyang, Windey — are all Chinese. Vestas, the Danish pioneer, fell to fifth.

China makes ~60% of the world’s electrolyzers — ~85% of the alkaline kind — at roughly a quarter of the German price. The catch: the world’s electrolyzer factories run at about 10% utilization. The demand isn’t there yet.

China’s solar giants lost billions in 2024 — Longi −8.6bn yuan, Tongwei −7bn — selling modules below cost. Beijing now fights its own price war (‘anti-involution’); the US slapped tariffs up to 3,521% on the exports.

China makes ~23% of the world’s machine tools but only ~6% of its high-end ones are home-grown; its exports average $300 a unit, its imports $76,700. The metal is easy; the precision is the moat.

Four foreign firms hold ~95% of China’s mid-to-high-end CNC controllers — the ‘brain’ of a machine tool. The wall isn’t the metal; it’s the motion-control software.

Xiaomi’s smart factory makes 10 million flagship phones a year with ‘100% of key processes automated.’ The viral ‘one phone per second, zero humans’ version is not what Xiaomi actually claims.

China is ~28% of global manufacturing but only ~6% of industrial-software output. Three firms control ~80% of the software that designs its chips — a dependence the US toggled on and off within weeks in 2025.

A Chinese team 3D-printed a ~4-metre titanium structure for the C919 jet and cut one part from 1,607 kg to 136 kg. In large-format metal printing, China plausibly leads the world.

China had 17,000+ ‘5G + industrial internet’ projects across all 41 industrial categories by end-2024, and targets 10,000 ‘5G factories’ by 2027 — the widest factory-floor 5G deployment on earth.

Haier’s COSMOPlat claims to link ~35,000 factories and 320 million consumers for ‘mass customization.’ The catch: the platform runs on an industrial-software and controls stack that is ~90% foreign.

China has designated 17,600+ ‘little giant’ SMEs — 3.5% of industrial SMEs generating 13.7% of the sector’s profits — specifically to backfill the components foreign suppliers could cut off.

China makes ~30% of the world’s goods but imports ~90% of high-end machine tools, ~95% of high-end controllers and ~94% of industrial software. It owns the factory; it rents what runs it.

Baidu’s Apollo Go passed 17 million rides at 250,000 fully-driverless trips a week — the volume Waymo hit in spring 2025. Three Chinese operators are now past 1,000 vehicles each.

Baidu’s RT6 robotaxi costs ~$28,000 to build, less than an ordinary EV. Operators now claim per-vehicle break-even — yet Pony.ai and WeRide still lost $77M and 1.7bn yuan in 2025.

Three Chinese firms hold ~76% of the automotive-LiDAR market, and a sensor that cost $50,000 a decade ago now sells for ~$200 — even as the Pentagon lists the market leader.

BYD put ‘God’s Eye’ assisted driving free across its lineup, down to a sub-$10,000 car. After a fatal crash, Beijing banned the terms ‘autonomous’ and ‘smart driving’ from marketing.

Inceptio-powered trucks passed 200 million commercial km, Pony.ai’s freight arm crossed 1 billion ton-km — with 20–50% labour savings. But almost all of it is still driver-supervised.

Pony.ai and WeRide raised ~$870M on Nasdaq in 2024, launched the Middle East’s first driverless service with Uber, then secured Hong Kong listings as insurance against US delisting risk.

China is wiring intelligence into its roads via a national ‘vehicle-road-cloud’ program across 20 cities — an approach that could lower per-car autonomy cost, if the infrastructure bill and the tech actually work.

China granted its first L3 permits in Dec 2025 and runs robotaxi pilots in ~20 cities under one national framework — then froze new permits nationwide after a mass robotaxi stall. Speed with a kill switch.

Waymo leads on documented safety across 220M+ driverless miles; China leads on scale, cost and supportive regulation. Both are real — and the metrics simply aren’t comparable.

SMIC built a 7nm smartphone chip with no EUV, using DUV multi-patterning. A genuine milestone — but one capped by yield and cost as it reaches toward 5nm.

China is on track for a third-plus of global mature-node capacity by 2027, building 30+ fabs for the chips in cars and appliances — and triggering a US Section 301 probe.

No EUV machine has ever entered China, and its best homegrown scanner sits near 90nm — a node ASML passed 15 years ago. Homegrown-EUV claims remain unproven.

China bought a record ~$49B of chip tools in 2024 and now makes ~35% itself — over 40% in etch and deposition, but near 18% in lithography. The average hides the shape.

YMTC shipped the world’s first 232-layer QLC NAND after being blacklisted, and is now a global top-three maker; CXMT’s DDR5 has taken it from <2% to ~5% of DRAM.

Three firms control 85%+ of the software every advanced chip is designed with. The US restricted EDA exports to China in May 2025 — then rescinded it six weeks later.

Denied advanced nodes, Huawei stacks 7nm chiplets to compete — its 384-chip AI cluster out-throughputs Nvidia’s flagship by brute force, at ~4x the power. Packaging narrows the gap; it doesn’t close it.

China holds 12 of the 24 top seats at RISC-V International and is drafting national policy to promote it. The catch: its best RISC-V chip is still made by TSMC.

‘Made in China 2025’ targeted 70% chip self-sufficiency; reality is ~15–27% depending on what you count. China imports more silicon than oil — and the leading-edge gap isn’t closing.

China claimed a task would take a supercomputer 2.5 billion years — but a 2024 classical algorithm can now simulate such experiments better than the hardware. The milestone is real; the scoreboard is provisional.

Zuchongzhi 3.0 claims a million-fold edge over Willow — on random-circuit sampling. Willow’s real breakthrough, error correction, is a race China’s chip didn’t enter.

Micius secured the first intercontinental quantum-encrypted call and a ~4,600 km network. But QKD secures only key exchange — and the ground backbone relies on ‘trusted nodes.’

Data stolen today can be decrypted by a future quantum computer. The West standardised post-quantum cryptography; China emphasises QKD — and the agencies genuinely disagree on which to trust.

China’s ‘$15 billion’ quantum war chest is the field’s most-cited stat — and one of its least verifiable, resting on a consulting estimate a top Chinese physicist thinks overstates reality 4x.

China files ~60% of the world’s quantum patents to America’s ~19% — but only ~7% of China’s travel internationally, versus ~49% of the US’s. The lead shrinks the moment you look closer.

Origin Wukong drew 20M+ remote visits from 139 countries — with the US on top, despite export controls. The real story is the ~80% domestic supply chain underneath it.

Sensing is the nearest-term quantum payoff — magnetometers, gravimeters, clocks — and China is fielding it from the sea floor to orbit. The exception to believe least: ‘quantum radar.’

The demos measure septillions of years; the revenue is a rounding error. Why quantum computing is still pre-revenue, how to size the timelines, and where the near-term value really sits.

Unitree cut its average humanoid price ~72% in two years and IPO'd up 542%. UBTech is shipping to BYD and Foxconn. Price is the strategy.

20–30 precision gearboxes sit inside each humanoid, and Japan long made nearly all of them. China's challengers are closing in — but the choke point just moved down a layer.

For the first time, China’s factories bought more domestic robots than foreign ones (57% share). One of the Big Four, KUKA, is already Chinese-owned.

Geek+ has led the world in warehouse-fulfilment AMRs by revenue for years running — No.1 in EMEA, and the first pure-play AMR company to ring the bell in Hong Kong.

The five biggest commercial service-robot makers in the world are all Chinese. Pudu’s revenue in the Americas grew 285% in a year.

A Chinese robot, not da Vinci, performed the world’s first FDA-authorised intercontinental surgery — 17,000 km from console to patient. The surgical-robot monopoly has a challenger.

China wrote the sub-1,000-metre sky into national policy, targeting 3.5 trillion yuan by 2035 — with a certified passenger air taxi and 900,000+ drone deliveries already flown.

Chinese drones have sprayed 500M+ hectares of the world’s farmland, with DJI alone holding 40%+ of the global market and 400,000 aircraft in the air.

Robots have no internet to learn from. China’s answer: 40+ state-backed ‘data factories,’ one targeting 3 million manipulation samples a year, and the largest open humanoid dataset.

How one open-weight release reset the market’s assumptions about what frontier AI costs — and why the ‘trained for the price of a car’ story is wrong.

Qwen is now the most-downloaded open model on earth. Why China gives its best models away — and what it wins by owning the default substrate.

Cambricon just posted its first-ever profit, Huawei is open-sourcing its CUDA rival, and models are being tuned for homegrown silicon. The domestic-chip flywheel is spinning.

A four-year timeline of curbs, workarounds and reversals — and why the second-order effect was to accelerate exactly what the controls meant to prevent.

China holds 101 of the world’s ‘lighthouse’ factories — more than any other country, by a wide margin — and the state has set explicit AI-penetration targets for 2027 and 2030.

China leads on AI papers, patents and researcher origin. The US still ships more frontier models — and employs most of the elite talent. The gap is closing fast.

A state-set 2025 mass-production deadline, 54% of the world’s industrial-robot installs, and humanoid prices down ~70% in two years. Embodied AI is China’s home game.

A national coast-to-desert compute grid, plus a $53 billion Alibaba capex plan that exceeds its entire prior decade of AI spend. And power is the binding constraint.

The 2023 Interim Measures made China first to bind generative AI — enforced as a pre-launch licence. 346 services filed before facing the public.

By a16z’s count, ~22 of the top 50 mobile Gen-AI apps are Chinese-built — but only 3 are mainly used in China. The app layer is an export business.
