Tighter tech curbs come with a sting

US' chip clamps will hurt innovation, spur Chinese alternatives, experts say

China-targeting moves by the United States to intensify export curbs related to advanced semiconductors have sharpened concerns by analysts that the latest measures will further crimp innovation in the US as China is forced to find alternatives.

The US government published sweeping export controls on Friday, including a measure to cut China off from certain chips made with US equipment, no matter where they were made.

The restrictions will bar US companies from exporting critical chip manufacturing equipment to China and also prohibit US citizens and companies from providing direct or indirect support to Chinese companies involved in advanced chip manufacturing.
