The decision marks the regulators' latest move to lock down US networks against the risk of Chinese espionage, a threat that national security officials began highlighting several years ago with the spread of cheap, Chinese-produced networking gear in small and rural wireless networks, reports CNN.

FCC said in a statement: "The Order on Revocation directs China Unicom Americas to discontinue any domestic or international services that it provides pursuant to its section 214 authority within sixty days following the release of the Order. Based oninput from Executive Branch agencies, thorough review of the company’s responses in this proceeding, the public record, and the FCC’s public interest analysis under the law, the Commission finds that today’s action safeguards the nation’s telecommunications infrastructure from potential security threats."

"In March 2021, the Commission found that China Unicom Americas had failed to dispel serious concerns regarding its retention of its authority to provide telecommunications services in the United States.  The Commission thus adopted procedures that allowed for China Unicom Americas, the Executive Branch agencies, and the public to present any remaining arguments or evidence in the matter," read the statement.
