HUAWEI Technologies Co. and ZTE Corp. on Monday both asked the U.S. Federal Communications Commission (FCC) not to finalize its designation of the Shenzhen-based tech giants as “risks” to U.S. national security.

In November, the FCC voted 5-0 to initially designate Huawei and ZTE as “national security risks” in a move that would bar their U.S. rural carrier customers from tapping an US$8.5 billion government fund to purchase equipment.

Huawei said in a nearly 200-page filing with the FCC the action was “designed to implement a campaign by certain U.S. government officials, including members of Congress, to single out Huawei for burdensome and stigmatizing restrictions, put it out of business in the United States, and impugn its reputation in the United States and around the world.” It called the effort “unlawful and misguided.”

ZTE asked the FCC in a filing Monday to “take additional time to assess ZTE’s enhancements in the area of U.S. export control and economic sanctions compliance and security controls in ZTE products.”

ZTE added it has “spent hundreds of millions of dollars to implement a compliance program relating to U.S. export control compliance regulations.”

The FCC left the final determination to its Public Safety and Homeland Security Bureau, which could determine not to finalize the risk designation.

Such a move would run counter to the Trump administration’s stance to date, after its blacklisting of Huawei in May sharply restricted the export of U.S. high-tech components to the company.

The administration has also tried with limited success to persuade its allies to bar Huawei, saying its equipment could potentially be used by China for “spying.”

Huawei has repeatedly denied those allegations, and scored a big win last week when the U.K. announced it was giving Huawei a role in its new generation of telecom infrastructure.

In its November vote, the FCC proposed requiring that U.S. carriers remove and replace equipment from both Huawei and ZTE from existing networks. (SD-Agencies)
