US regulators on Friday listed Huawei among Chinese telecom gear firms deemed a threat to national security, signalling that a hoped for softening of relations is not in the cards.
A roster of communications companies thought to pose "an unacceptable risk" to national security included Huawei Technologies; ZTE; Hytera Communications; Hangzhou Hikvision Digital Technology, and Dahua Technology.
"This list is a big step toward restoring trust in our communications networks," said Federal Communications Commission acting chairwoman Jessica Rosenworcel.
"This list provides meaningful guidance that will ensure that as next-generation networks are built across the country, they do not repeat the mistakes of the past or use equipment or services that will pose a threat to US national security or the security and safety of Americans."
The five Chinese companies that provide communications equipment or services were on a roster compiled by the FCC and the Homeland Security Bureau as per US law.
Huawei chief and founder Ren Zhengfei last month called for a reset with the United States under President Joe Biden, after the firm was battered by sanctions imposed by Donald Trump's administration.
In his first appearance before journalists in a year, Ren Zhengfei said his "confidence in Huawei's ability to survive has grown" despite its travails across much of the western world where it is maligned as a potential security threat.
The comments came as the firm struggled under rules that have effectively banned US firms from selling it technology such as semiconductors and other critical components, citing national security concerns.
Insisting that Huawei remained strong and ready to buy from US companies, Ren called on the Biden White House for a "mutually beneficial" change of tack that could restore its access to the goods.
Continuing to do so, he warned, would hurt US suppliers.
