(Reuters) - The Federal Communications Commission (FCC) said Tuesday it had named Chinese telecom companies Pacific Network Corp, its wholly-owned subsidiary ComNet (USA) LLC and China Unicom (Americas) to its list of communications equipment and services deemed threats to U.S. national security.

The designations are under a 2019 law aimed at protecting U.S. communications networks. In March 2021, the FCC designated five Chinese companies under its so-called "Covered List" - including Huawei Technologies Co, ZTE Corp, Hytera Communications Corp, Hangzhou Hikvision Digital Technology and Zhejiang Dahua Technology Co.
