US raises concerns ASML's EUV tool may have reached China

U.S. officials pressed ASML about a potential European UnionV lithography tool or related gear ending up in China in possible breach of export rules; ASML denies shipping EUV machines or components to China and says it complies with all controls. Washington says it has evidence of shipments that could support EUV systems, but details are sensitive. The dispute heightens tensions with the EU over semiconductor exports and comes as Congress weighs tighter restrictions on chip-making tools, potentially affecting ASML’s China business and broader transatlantic relations.
