According to RFA, Tarun Chhabra, a National Security Council’s senior official, said that the Biden administration could soon provide more clarification on new regulations for chip exports to China.
Earlier this year, the U.S. Department of Commerce asked U.S. companies not to export advanced semiconductors with sub-14 nanometer processes to China unless they obtained a permit.
Chhabra said that the U.S. Department of Commerce had sent letters to two major chipmakers, Nvidia and AMD, asking them to stop exporting certain chips to China.
Specifically, the chips that could be used in natural language processing and nuclear weapons research.
RFA commented that the move signifies that the Biden administration will further tighten controls on chip exports to China.
In a related development, U.S. semiconductor companies refuse to import chip materials suspected of being sourced from China.
U.S. customers are asking Korean companies for certificates of origin to prove that their chip products are not of Chinese origin.
Some Korean companies are changing the certificates of origin for their products made in Taiwan.
On the new certificate, the word “Republic of China,” the official name of Taiwan, has even been changed to “Taiwan” to avoid confusion with China.
