The Biden administration has banned approvals of new telecommunications equipment from China’s Huawei Technologies HWT.UL and ZTE 000063.SZ because they pose “an unacceptable risk” to U.S. national security.

The U.S. Federal Communications Commission (FCC) said Friday it had adopted the final rules, which also bar the sale or import of equipment made by China’s surveillance equipment maker Dahua Technology Co 002236.SZ, video surveillance firm Hangzhou Hikvision Digital Technology Co Ltd 002415.SZ and telecoms firm Hytera Communications Corp Ltd 002583.SZ.

The move represents Washington’s latest crackdown on the Chinese tech giants amid fears that Beijing could use Chinese tech companies to spy on Americans.

“These new rules are an important part of our ongoing actions to protect the American people from national security threats involving telecommunications,” FCC Chairperson Jessica Rosenworcel said in a statement.

Huawei declined to comment. ZTE, Dahua, Hikvision and Hytera did not immediately respond to requests for comment.

Rosenworcel circulated the proposed measure — which effectively bars the firms from selling new equipment in the United States — to the other three commissioners for final approval last month.

The FCC said in June 2021 it was considering banning all equipment authorizations for all companies on the covered list.

That came after a March 2021 designation of five Chinese companies on the so-called “covered list” as posing a threat to national security under a 2019 law aimed at protecting U.S. communications networks: Huawei, ZTE, Hytera Communications Corp Hikvision and Dahua.

All four commissioners at the agency, including two Republicans and two Democrats, supported Friday’s move.
