The Netherlands has intensified diplomatic efforts urging the United States to drop export restrictions on ASML, a critical supplier of advanced chipmaking equipment. The move underscores growing tensions between allies over semiconductor trade controls designed to limit China's access to cutting-edge technology.

ASML, based in Veldhoven, holds a near-monopoly on extreme ultraviolet (EUV) lithography machines essential for producing the most advanced chips. The US curbs, part of a broader campaign to contain China's semiconductor ambitions, have restricted ASML from selling its top-tier tools to Chinese buyers without a license.

Dutch officials argue the restrictions harm Europe's strategic autonomy and economic interests, according to people familiar with the talks. The Netherlands has leveraged its role as a key US ally to push for narrower rules, seeking exceptions for older-generation equipment that is less sensitive to national security concerns.

The dispute reflects a broader global divide over chip export controls — the US deems them critical to slowing Beijing's military modernization, while European tech hubs worry about lost revenue and technological isolation. ASML has warned that supply-chain fragmentation could slow innovation and inflate costs for chip buyers worldwide.

Counterargument: US intelligence agencies and some lawmakers argue that any softening of ASML restrictions could allow China to leapfrog in advanced chip production, undermining a key pillar of American national security strategy.
