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 that use ultraviolet light to etch tiny circuits on next-generation processor chips, which is holding back Chinese efforts to develop chips for smartphones, AI, and other advanced applications. The Chinese ambassador to the Netherlands earlier threatened possible unspecified retaliation, but the ministers gave no indication they discussed that in their 2 1/2-hour meeting.
