ASML Was Told to Close the Door to China. So China Walked Through It While It Was Still Open.

In the spring of 2024, a single country accounted for nearly half of every lithography machine ASML sold. That country was China — the one the United States had spent five years trying to wall off from ASML's machines. In Q2 2024, China was 49% of ASML's net system sales, its highest-ever quarterly share⁴, reached while a tightening web of Dutch and US export controls was supposed to be squeezing it shut. The wall was going up. The traffic through the gate had never been heavier.

The official story is that the West cut ASML off from China and ASML's China business is dying. Almost every part of that is the reverse of what the numbers say. The controls did not cut China off; they announced, years in advance, exactly which machines would soon be unavailable — and gave China a long, clear runway to buy a decade's worth of them while the door was still open.

A ban that was announced before it arrived

Start with the thing everyone gets backwards. People say ASML was "barred from selling to China in 2019." What actually happened was far narrower. Under US pressure, the Dutch government simply declined to renew ASML's export license for EUV — its most advanced, extreme-ultraviolet machine — before that license expired on June 30, 2019.⁷ And here is the detail that detonates the popular framing: ASML had never shipped a single EUV machine to China in the first place.⁷ The 2019 "ban" closed a door China had not yet walked through. The DUV machines — the older, deep-ultraviolet workhorses that make the vast majority of the world's chips — kept flowing, unrestricted, for four more years.

When the Dutch controls finally did arrive, they arrived on a schedule. New regulations took effect September 1, 2023, requiring licenses for the advanced NXT:2000i and later DUV systems.¹ But the most widely-used immersion models, the NXT:1970i and 1980i, were not captured by Dutch licensing until September 7, 2024 — a full year later.² Each rule named its target and gave a date. To a Chinese fab planner, that is not a wall. That is a countdown clock with the inventory list printed on it.

The numbers tell on everyone

Watch what the buyers did with that warning. China was a modest slice of ASML's revenue in 2022. Then it exploded: China accounted for 41% of ASML's net system sales in 2023.³ ASML's own DUV unit sales jumped from 305 machines in 2022 to 396 in 2023³ — a surge that did not come from sudden structural demand but from front-loading, the rational scramble to buy tomorrow's banned tools at today's open prices. This is the central, awkward fact of the whole episode: the restriction created the demand it was meant to suppress.

ASML did not merely benefit from this; it stood in the middle of it, with contradictory orders pulling each way. It is the world's sole maker of EUV and makes roughly 90% of the world's DUV immersion systems⁹ — which makes it indispensable to Western chip strategy and impossible to ignore. Yet it is legally subordinate to The Hague and, through it, to Washington. And the Dutch approach is country-neutral: there is no blanket presumption of denial against Chinese buyers, with applications judged case by case. As many as 41 Chinese companies hold a valid DUV import license, and in 2024 ASML sold nearly $3 billion of equipment and services to Chinese entities of concern.⁹ A monopoly that is told what to sell, to a country its rules invite it to keep selling to.

The one machine the controls actually held

If the DUV story is a story of leakage, the EUV story is the opposite — and it is the part of the policy that genuinely worked. EUV is the single chokepoint that has not given way. ASML maintains that it has never shipped an EUV system, or even EUV-specific components, to China. It said so flatly in a June 2026 denial issued after a Bloomberg report that the US Commerce Secretary had raised concern with ASML executives that the technology might have reached China; no public evidence of any such export has been presented.¹⁰ The 2019 license that was never renewed has held for the better part of a decade. The difference between the two stories is the difference between a tool you can stockpile and one you cannot get at all.

Isn't ASML just a victim caught in the middle?

The fair objection is that ASML is a pawn — a Dutch company doing what its government and Washington tell it, profiting incidentally from a policy it did not design. There is real truth in that: ASML applies for the licenses, ASML obeys the rules, and ASML repeatedly says it complies with every applicable law.⁵ But the pawn framing is too tidy. By one account drawn from a book by two former Bloomberg journalists, ASML in 2023 pushed past a "gentlemen's agreement" with the US on how many DUV machines it would sell to China before the controls fully bit — angering US officials — and then reportedly offered to act as Washington's "eyes and ears" in China to stave off tighter rules.⁸ That account rests on anonymous sources and should be held loosely. But even held loosely, it points at something real: a firm that is indispensable does not sit still while others decide its fate. It plays the seam between two regimes, because the seam is where its leverage lives.

And the front-loading does not last. China's share fell back to 29% of net system sales for full-year 2024³ as the panic-buying exhausted itself, and ASML still guides to €30–35 billion in 2025 sales with a €44–60 billion scenario for 2030⁵ — a business whose growth was never really about China. The stockpile was a one-time pull-forward, not a permanent franchise. The controls were self-defeating in the near term and structurally sound in the long one, which is the most uncomfortable verdict of all: they failed at the thing that was easy to measure and succeeded at the thing that was hard to.

ASML spent five years being described as the company shut out of China while it was, in fact, the company China could not buy from fast enough. The wall did its job exactly where the goods were truly scarce — EUV, denied and undelivered — and did the opposite of its job everywhere a buyer could stockpile against a published deadline. The chip war's lesson is not that chokepoints don't work. It's that a chokepoint only chokes what can't be carried out in advance. Announce the rest, and you don't close the door. You just tell everyone how long they have to run through it.
