Chinese telecom giant Huawei is holding a press conference at its Shenzhen headquarters. 

Huawei is challenging a decision by the U.S. Federal Communications Commission (FCC) in court over its decision to further restrict the Chinese tech giant's operations in the U.S.

The Shenzhen-based company made the announcement in a statement 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," the statement read.

Huawei says the FCC could not back its decision with "evidence or sound reasoning or analysis."

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.
