Mara ReyesIn December 2018, the Financial Times reported that US export controls could slow China's ambitions to mass-produce cutting-edge chips. Today, Huawei's Ascend 950PR chip is entering mass production with prices rising 20% on bulk orders from Chinese tech giants to run DeepSeek's V4 model. Chinese semiconductor companies just reported record 2025 revenue. And the US Congress introduced a bill to ban even more exports — escalating the very controls that produced this outcome.
The Design
The export control regime was an infrastructure decision. Like a levee or a firewall, it was engineered to contain a specific threat under a specific set of assumptions. The threat: China developing an independent advanced semiconductor capability. The assumption: that the technology was sufficiently complex that cutting off a handful of chokepoints — EUV lithography from the Netherlands, advanced fabrication from Taiwan, AI chips from California — would create a dependency gap too wide to bridge domestically.
In 2018, the assumption held. China's most advanced domestic chipmaker, SMIC, was producing at 28nm — roughly a decade behind the global frontier. Huawei depended on TSMC to fabricate its HiSilicon designs. The supply chain ran through Western bottlenecks, and the US controlled access to most of them.
In October 2022, the controls tightened dramatically. The Financial Times reported that experts painted "a dire picture" for China's semiconductor industry under the new restrictions. The assessment was not unreasonable. It was also the last moment the controls matched the conditions they were designed for.
The Response
Within weeks of the 2022 restrictions, Nikkei Asia reported that Huawei had begun stealthily building a domestic chip supply chain. The planning had started earlier — Beijing's "frenzied drive" to free itself from imported chips was visible by late 2020. But the controls converted an aspiration into a mandate. The Chinese government and its technology companies went from wanting self-sufficiency to needing it.
The response followed the same pattern as any infrastructure under stress. Not one breakthrough. A cascade of adaptations, each building on the last:
-
MAY 2023The New York Times reports on China's plans to "de-Americanize" its domestic chip industry. The goal shifts from catching up to decoupling entirely.
-
OCT 2023Bloomberg reveals that SMIC used ASML's older DUV machines to produce a 7nm chip for Huawei — a node the controls were supposed to make impossible without EUV.
- Jun 2024 The Wall Street Journal reports on China's chip industry aiming for self-sufficiency and cutting its reliance on Western technology.
-
SEP 2024Bloomberg reports China is discouraging local companies from purchasing Nvidia's chips — not because they can't access them, but because the government wants to accelerate the shift to domestic alternatives.
- Dec 2024 Four top Chinese industry associations tell companies they should be wary of using US chips. The messaging shifts from "we can't buy them" to "we shouldn't buy them."
The phase transition happened in late 2024. Chinese industry shifted from workaround — how to access restricted technology despite the controls — to substitution — how to build domestic alternatives that don't need Western technology at all. The controls didn't just fail to prevent development. They changed the development's goal.
The Ecosystem
By 2025, the adaptations had compounded into something the original controls didn't model: a domestic semiconductor ecosystem with its own momentum.
In March, Chinese equipment manufacturer SiCarrier debuted roughly 30 "domestically developed" chip manufacturing tools — the kind of equipment China previously imported from ASML and Applied Materials. By May, the Financial Times reported that Alibaba, Tencent, Baidu, and other major Chinese companies were testing domestic chip alternatives. The entire supply chain was reorganizing around domestic inputs.
By September, SemiAnalysis published a deep dive into Huawei's Ascend AI chip production documenting what had emerged: a vertically integrated domestic supply chain producing AI chips at scale, using domestically developed tools and fabrication. In November, Nikkei reported on Huawei's efforts to build an independent Chinese chip supply chain — the word "independent" doing the structural work. Not "competitive." Not "catching up." Independent.
The same month, the Wall Street Journal reported that the Chinese government was intervening in how SMIC distributes its chips — a sign that demand for domestic semiconductors had grown large enough to require state-level allocation. The ecosystem had its own supply constraints. Not because it was failing. Because it was working.
Record Revenue
Huawei's Ascend 950PR — a domestic AI chip fabricated on a domestic process — is seeing prices rise 20% because Chinese tech giants are placing bulk orders to run DeepSeek's V4 model. The demand isn't speculative. It's operational: China's most capable AI model runs on China's most capable chip.
CNBC reports that Chinese semiconductor companies like SMIC posted record 2025 revenue, driven by the demand that export controls were supposed to prevent. Startups and researchers who can't access the most advanced Western chips are building on domestic hardware, optimizing for the chips they can get, creating a software ecosystem adapted to Chinese silicon.
A year ago, DeepSeek's R1 model shocked the US tech establishment by demonstrating frontier-class performance built under resource constraints imposed by export controls. DeepSeek V4, running on Huawei's domestic Ascend chips, is the next phase: not just working around the constraints, but building on a fully domestic stack. The controls created the conditions for both.
The Escalation
The US response is a bill to ban exports of DUV lithography technology to China — the older machines that SMIC used to produce its 7nm chip in 2023. The logic follows the same structure as the original controls: identify a chokepoint, restrict access, assume the restriction will hold.
In 2018, restricting access to lithography meant restricting access to fabrication. In 2026, China has spent four years and unknown billions building domestic alternatives to every restricted input. SiCarrier's 30 domestic tools include lithography alternatives. The gap between what China can build independently and what it needs from the West has been closing for years — under pressure from the controls themselves.
Each escalation assumes the target is the same as it was when the previous control was designed. The target has been adapting since day one.
Banning DUV exports in 2026 is not the same action as banning EUV exports was in 2022. The system it targets is no longer the system it was designed to contain.
The Third Outcome
In structural engineering, proof loading means applying stress to verify a structure can withstand its design loads. If it holds, the test confirms soundness. If it fails, you've found the weakness. But there is a third outcome that proof loading doesn't model: the structure adapts. It reorganizes under stress. It finds load paths the designers never specified.
Eight years separate that Financial Times headline and today's news of record Chinese semiconductor revenue, Huawei's mass-produced AI chip, and DeepSeek V4 running on domestic hardware. In that time, every phase of escalation — EUV restrictions, entity list additions, DUV bans now proposed — produced the same structural response: faster development of the thing the controls were supposed to prevent.
The controls were designed for a world where China depended on Western semiconductor technology. That world existed in 2018. The containment created the pressure. The pressure created the adaptation. The adaptation created an industry that no longer needs the technology it was denied.
