US urges allies to ban companies from servicing key chip-making tools for China

Washington has been locked in a years-long technology war with Beijing, seeking to stop China from making more advanced chips that could be used to strengthen its military.

US allies resist Biden’s urge to tighten chip curbs on China

The Biden administration announced new restrictions on shipments of American-made chip-making tools to advanced Chinese chip factories in 2022, and convinced key chip-making tool producers Japan and the Netherlands to follow suit with their own controls.

The US rules made it difficult for US companies to continue servicing tools that Chinese firms bought prior to the new regulations, but the Dutch and Japanese rules did not include similar restrictions.

That has spurred US officials to convince allies to mirror US curbs.
