Huawei sues US over equipment ban in escalating legal clash

Huawei Technologies Co. sued the US government for barring its equipment from certain networks, delivering a legal riposte to American accusations it aids China in espionage.

The lawsuit is aimed at a US statute that blocks government agencies from using equipment from Huawei and its domestic rival ZTE Corp., according to a complaint filed in federal court in Texas. Huawei argues in the suit that it’s unconstitutional to single out a person or a group for penalty without a fair trial.

The action signals a more aggressive response from the company toward its US accusers, who have been trying to persuade other countries to ban Huawei gear from crucial fifth-generation communications networks.
