Huawei announces it will sue the U.S. government

Huawei is taking its fight against the U.S. to the courts.

The Chinese tech giant announced on Thursday it would be filing a lawsuit against the U.S. government, which has accused Huawei of being a spy threat and placed restrictions on its products.

Huawei rotating chairman Guo Ping said the company wants to challenge the constitutionality of the National Defense Authorization Act, which saw Huawei's products banned in the U.S., and also to seek an injunction against those restrictions.

Guo said the U.S. government has failed to provide evidence on it being a security threat, and has convinced other countries to not use its products.

The announcement comes after Huawei's CFO Meng Wanzhou faced extradition proceedings in Vancouver, Canada on Wednesday.

Meng was arrested by Canadian authorities in December, and will potentially be extradited to the U.S. on charges of violating sanctions against Iran. She also faces charges of bank and wire fraud, as well as conspiracy to commit bank and wire fraud.

Huawei has also fought back in newspapers around the world, with ads imploring readers to "don't believe in everything you hear" as published in the Wall Street Journal, or in one New Zealand paper, equating a ban on the Huawei to a ban on the country's national rugby team.
