  The Netherlands will further restrict ASML’s exports of advanced chipmaking equipment to China, aligning with US efforts to curb China's technological advancement. The new regulations, expected to be formalized by summer, will specifically target deep ultraviolet (DUV) lithography systems, expanding existing restrictions beyond the most advanced extreme ultraviolet (EUV) machines. While the exact models affected remain unclear, the move signals a significant escalation in the ongoing tech war between the US and China.

  In a significant development concerning the global semiconductor industry and escalating technological tensions, the Netherlands government has announced its decision to implement new export controls targeting advanced chipmaking equipment, aligning itself with similar restrictions imposed by the United States last year. This move specifically affects ASML Holding NV, a Dutch company that holds a near-monopoly on the production of the most sophisticated lithography systems essential for manufacturing cutting-edge chips. These systems, utilizing extreme ultraviolet (EUV) lithography and deep ultraviolet (DUV) lithography, are crucial for producing the smallest and most powerful semiconductors used in advanced computing, artificial intelligence, and other high-tech applications.

  The newly unveiled Dutch regulations, while not mirroring the US restrictions exactly, will restrict the export of certain advanced DUV lithography systems, specifically the TWINSCAN NXT:2000i and subsequent iterations. These sophisticated machines are not quite as advanced as ASML's flagship EUV systems, but they remain critical for producing leading-edge chips, making the export restrictions a notable impediment to certain chip manufacturers. This alignment between the Netherlands and the United States represents a concerted effort to limit the access of certain nations, particularly China, to this vital technology, thereby potentially impacting their ability to advance their own domestic semiconductor industries. While the regulations do not explicitly name China as the target, the implications are clear, given the ongoing geopolitical dynamics and the strategic importance of semiconductor technology in the global economic and military landscape.

  This decision follows months of diplomatic pressure from the United States on the Netherlands to join its efforts in restricting China's access to advanced chipmaking technology. The move underscores the growing international concern over the potential military applications of these advanced semiconductors and represents a significant escalation in the ongoing technological competition between the United States and China. The Dutch government emphasized its commitment to national security and stressed that the new regulations are necessary to protect vital technological interests. ASML, while acknowledging the new regulations and their potential impact on its business, has stated that it does not expect the restrictions to materially affect its previously stated financial outlook for 2025. However, the long-term implications for the global chipmaking landscape remain to be seen, as these export controls could significantly reshape the dynamics of semiconductor production and international trade.
