The "guardrails" proposed by the U.S. are sci-tech blockade measures and protectionist in nature, said Wang Wenbin, spokesperson of the Chinese foreign ministry on Wednesday at a press briefing.

Wang said the U.S. attempted to fragment the industrial chains at China's expense. "The U.S. has overstretched the concept of national security, abused export control measures, and even coerced some of its allies to block and contain China."

The U.S. Commerce Department on Tuesday released proposed rules to prevent $52 billion in semiconductor manufacturing and research funding from being used by China and other countries deemed of concern, according to Reuters.

The proposal limits recipients of U.S. funding from investing in the expansion of semiconductor manufacturing in certain foreign countries and limits recipients of incentive funds from engaging in joint research or technology licensing efforts with a foreign entity of concern.

This measure covers chips "including current-generation and mature-node chips used for quantum computing, in radiation-intensive environments, and for other specialized military capabilities."

At the press briefing, Wang said such measures "gravely violate the law of the market economy and the principle of fair competition."

Wang said the containment and suppression from the U.S. will only "strengthen China's resolve and capability to seek self-reliance and technological innovation."

"To preserve one’s own hegemony at the expense of normal international economic and sci-tech cooperation will only backfire," Wang said. He called on all parties to work with China to safeguard the stability of global industrial and supply chains as well as defend shared interests.
