Huawei just upped the ante in its fight with America over its telecommunication devices.

The Chinese tech giant announced on Thursday that it has filed a lawsuit against the US government, which has banned its federal agents from using the equipment citing privacy concerns.

The US has ramped up political pressure on Huawei in recent months, requesting the extradition of its CFO Meng Zhou, who was arrested in Canada in December, and lobbying allies to reject its 5G equipment.

In a press conference on Thursday, the company claimed the US government has failed to produce evidence to back up concerns that the company poses a security threat, and it said the US government has acted unconstitutionally.

Huawei has denied allegations of installing back door software or spyware onto its devices.
