The United States has told ASML, the Dutch company that makes the world's most advanced chip-making machines, that it is worried one of its top tools may have ended up in China. ASML says that is not true.
According to a report from Bloomberg News, US officials raised the concern with ASML's senior leaders. The worry is that one of ASML's extreme ultraviolet (EUV) lithography machines — its most advanced and tightly controlled product — may have made its way into China, in violation of strict US-led export restrictions.
ASML Denies Any Violation
ASML has firmly denied that any of its top machines are in China without proper authorization. The company says it follows all export control laws and has not shipped an EUV tool to China. The Dutch government also requires licenses for exporting such advanced semiconductor equipment, as noted in a report from Reuters.
The US and its allies have for years restricted the sale of EUV machines to China, fearing they could be used to build advanced chips for military purposes. ASML is the only company in the world that makes these machines, which are essential for producing the most powerful computer chips.
Commercial Logic Against the Claim
There is a strong commercial reason why ASML would not risk sending an EUV tool to China without permission. The company's entire business depends on its export licenses. If it were caught violating those rules, it could lose the ability to sell its machines anywhere in the world. That would be a catastrophic blow to its revenue and reputation.
As the original story notes, "There's a commercial logic that cuts against the idea that ASML would risk its export license to arm a Chinese customer." In other words, the potential cost of getting caught is far higher than any short-term gain from selling one machine to China.
Our Take: A Serious Allegation, But Unlikely
This is a serious allegation from the US government. If true, it would mean a major breach of the most tightly controlled technology export regime in the world. But the evidence so far is thin. The US has not provided any proof that an EUV machine is actually in China. ASML has a strong incentive to follow the rules, and it has denied the claim outright.
In our view, this looks more like a diplomatic signal than a confirmed fact. The US may be trying to pressure ASML and the Dutch government to tighten controls even further. But without concrete evidence, it is hard to take the claim at face value. For now, the most reasonable position is to trust ASML's denial — unless the US comes forward with proof.
