China demands access to Dutch chipmaking tech despite security concerns.

China's foreign minister has urged his Dutch counterpart to provide access to advanced chipmaking technology that has been blocked on security grounds, warning against unfounded fears of Beijing spoiling relations. The Netherlands has not changed its restriction on the supply of lithography machines available only from a single Dutch company that use ultraviolet light to etch tiny circuits on next-generation processor chips. Lack of that tool is holding back Chinese efforts to develop chips for smartphones, artificial intelligence, and other advanced applications.
