China has urged the United States to stop barring U.S. investment in Chinese companies after the Biden administration expanded a blacklist to 59 Chinese firms for alleged ties to domestic military or surveillance technology sectors. A spokesperson of the Chinese Foreign Ministry said China will take necessary measures to resolutely safeguard the legitimate rights and interests of Chinese companies. U.S. President Joe Biden signed an executive order on Thursday adding more companies to a Trump-era investment ban on 31 Chinese companies, which was released last November.
