Summary

Lutnick Accuses ASML

US Commerce Secretary Howard Lutnick told ASML leaders a top-of-the-line EUV lithography machine may have reached China, alleging an export-control breach.
ASML CEO Christophe Fouquet said the firm has never shipped an EUV machine or related equipment to China and monitors every system continuously.
After the claim, ASML shares dropped up to 2.7% in early Amsterdam trading, while the U.S. Commerce Department has not disclosed evidence or announced enforcement.

Summary

China Builds EUV

Chinese scientists built a prototype extreme ultraviolet (EUV) lithography machine with former ASML engineers.
The prototype was first reported in December as part of a domestic effort despite U.S. export restrictions.
In April, Washington proposed a law forcing allies to align export controls and specifically naming ASML equipment.
Experts warn that a home-grown Chinese EUV capability could reshape the global AI-chip supply chain and cut reliance on Dutch technology.

Summary

ASML Faces Restrictions

EUV lithography systems weigh 180 tons and require on-site ASML maintenance, preventing covert transport.
ASML is preparing documentation to prove full compliance with global trade rules after the U.S. Commerce Secretary’s concerns.
The U.S. MATCH Act, unveiled in April 2026, would ban DUV immersion machines and forbid DUV servicing in China.
China’s ASML system sales share fell from 36 percent to 19 percent in Q1 2026, showing tighter export controls.

History

Historical Context

In 1999 the United States, using the Export Administration Regulations administered by the Bureau of Industry and Security, blocked shipments of high-performance computers to China, denying 2,300 licenses and labeling 15 % of supercomputer exports as critical. The 2026 claim by Commerce Secretary Howard Lutnick that an ASML EUV lithography tool reached China echoes that earlier crackdown and reflects post-2018 tightening of EAR controls over dual-use technologies.
