The Chinese telecom Huawei on Monday urged the US Federal Communications Commission (FCC) not to finalize its designation of the company as a national security threat.

The FCC voted unanimously in November to designate Huawei, as well as ZTE Corp, national security risks because of their ties to the Chinese government and its military, as well as laws in China that govern the companies’ relationship with its intelligence services. The FCC left finalization of the decision to its Public Safety and Homeland Security Bureau, to which Huawei has now communicated its complaints.

The Bureau announced last month that it was open to comments on the designation and gave the companies until February 3 to provide responses. Huawei submitted its filing on Monday, in which it called the designation “misguided” and an attempt to “impugn its reputation.” ZTE submitted a letter as well, declaring that its “senior leadership is committed to ensuring that [the] Company conducts business only in compliance with all applicable laws” where it operates. The company said it “would welcome the opportunity to meet with the Commission, listen to, and try to address any concerns that it might have.”

Huawei, for its part, accused the US government of singling it out with “burdensome and stigmatizing restrictions.” The FCC’s bureau now has 120 days to reach a final decision on the designation.
