"Such restrictions and forced de-coupling for political purposes
violate the principles of the market economy and fair
competition," the ministry said in a response to Reuters'
questions.
The U.S. has said it does not want to block China's economic
development, and China hopes the U.S. will adhere to this rather
than saying one thing and doing another, it said.
Washington on Tuesday said it plans to halt shipments to China
of more advanced artificial intelligence chips designed by
Nvidia and others.
It also restricted a broader swathe of advanced chips and
chipmaking tools to a greater number of countries including Iran
and Russia, and blacklisted Chinese chip designers Moore Threads
and Biren.
China's CSI Semiconductor Index dropped 1.4% on Wednesday
following the announcement, while the STAR Chip Index lost 1.2%.
An index tracking China's artificial intelligence (AI) companies
closed 1.8% lower, after hitting a nine-month low. AI stocks
were further hit after the U.S. announced further controls on
Nvidia chip exports to China, UBS wrote in a note to clients.
Yang Wang, a senior analyst at Counterpoint, said he expected
only limited disruption to the Chinese AI industry given that
many had been bracing for the curbs and stockpiling chips.
Still, the impact could be more material over the medium to
longer term and could cause the gap between China and global
peers in AI to grow in coming years, he added.
Charlie Chai, analyst at 86Research, said the restrictions would
likely further boost the self-sufficiency agenda being pushed by
Chinese President Xi Jinping.
While Nvidia will be unable to sell some AI chips to China, the
new rules will also prevent cutting-edge technology from being
used to manufacture chips designed by two of its most capable
rivals, Biren and Moore Threads, well-funded Chinese startups
founded by Nvidia veterans.
Biren said on Tuesday that it was assessing the possible impact
on the company and would appeal to the U.S. government to
re-examine the decision. Moore Threads said it was communicating
with all parties involved and evaluating the impact.
