The Netherlands is actively lobbying the US to halt further expansion of semiconductor equipment export controls that would curb ASML Holding NV's ability to sell immersion DUV machines to China, according to Bloomberg.

This diplomatic push comes amid ongoing US efforts to restrict advanced chipmaking technology to Beijing. The Netherlands, home to ASML, seeks to protect a key economic asset and maintain its position in the global semiconductor supply chain.

At stake are restrictions on immersion deep ultraviolet (DUV) lithography machines, which are less advanced than ASML's extreme ultraviolet (EUV) systems but remain crucial for producing many chips. ASML dominates this niche, making any new controls a direct hit to its revenue stream.

If Washington proceeds, it could strain US-Dutch relations while potentially accelerating China's push for domestic chip equipment development. ASML's business with Chinese customers faces significant headwinds amid geopolitical tensions.

Counter-argument: US officials argue that stricter controls are necessary to prevent China from using these machines to advance its military capabilities, a security concern that may override economic considerations for allies.
