Has China got its hands on Chip tools U.S. tried to deny it?

For years, Washington has treated one piece of machinery as the crown jewel of chip-war containment: the extreme ultraviolet lithography, or EUV, system made by Dutch firm ASML. These machines, roughly the size of a school bus and weighing 180 tons, are the only tools in the world capable of printing the circuit patterns needed for the most advanced semiconductors, the kind that power Nvidia chips and Apple devices. Export bans dating back to the first Trump administration have kept every single one of them out of China. Until, perhaps, now.

US Commerce Secretary Howard Lutnick has told ASML's senior leadership, in a series of recent meetings, that Washington believes one of these top-of-the-line machines may have slipped into China in violation of US-led export restrictions, according to people familiar with the discussions.

ASML has firmly denied it. "ASML has never shipped an EUV machine to China, nor have we shipped to China any component, module or equipment specially designed to be used in an EUV machine," the company told Reuters in a statement.

But US officials appear unconvinced. Multiple senior administration officials, speaking anonymously, said they possess evidence suggesting ASML has not been acting in good faith, though they have so far declined to produce that evidence publicly, citing the sensitivity of the matter. They have also declined to confirm whether they have actually seen proof of an EUV system operating inside China.

The standoff lands at a delicate moment. ASML has expanded its presence in China in recent years, including a repair and reconditioning facility in Beijing, which the company insists complies fully with export law. Lawmakers in Washington have simultaneously pushed the proposed MATCH Act, aimed at tightening allied export controls on chipmaking tools worldwide.

If the allegations prove true, it would mark the most significant breach yet of the West's strategy to keep China's chip ambitions in check.
