The U.S. plans to cancel the exemption licenses for Samsung, SK Hynix, and TSMC's chip factories in China.

On June 20, according to The Wall Street Journal, the United States is preparing to take action against its allies’ chip factories in China, as part of a broader crackdown on technology export controls to China.

The United States plans to revoke the exemption licenses for companies such as Samsung, SK Hynix, and TSMC, which currently allow them to use American technology in their factories in China without applying for permits on a case-by-case basis.
