Huawei is taking legal action against the U.S. Federal Communications Commission (FCC) over its decision to further restrict the Chinese tech giant's operations in the U.S.

The Shenzhen-based company made the announcement on Thursday, saying it is mounting a legal challenge to the "unlawful order."

"In a petition filed in United States Court of Appeals for the Fifth Circuit, Huawei asks the court to hold the FCC's order unlawful on the grounds that it fails to offer Huawei required due process protections in labeling Huawei as a national security threat," Song Liuping, chief legal officer at Huawei said at a press conference in Shenzhen.

Last month, the FCC banned U.S. rural carriers from using federal funds to buy equipment from companies that "pose a national security threat," naming Huawei and ZTE as such firms.

Song said the FCC could not back its decision with "evidence or sound reasoning or analysis."

"The U.S. government has never presented real evidence to show Huawei is a national security threat. That's because this evidence does not exist," Song said, arguing the ban was politically motivated.

Song noted that Huawei is willing to work together with the U.S. government on the matter.

Glen Nager, lead counsel for Huawei and a partner at Jones Day, said at the press conference that the FCC has no authority to make judgments on national security. "That's at the discretion of the president," he said.

Vice President of Huawei's Corporate Communications Karl Song stressed the long-tern and close cooperation between Huawei and rural carriers in the U.S., saying the ban will harm the business and people in those remote areas as well.
