Lawyers for the Chinese electronics giant Huawei are due in court in a US case charging the company with violating Iran trade sanctions. The company is to be arraigned Thursday morning on an indictment filed in federal court in Brooklyn.

Prosecutors have accused Huawei of using a Hong Kong front company to trade with Iran in violation of US sanctions. They allege the daughter of the company’s founder lied to banks about those dealings while serving as the company’s chief financial officer.

The daughter was arrested in Canada earlier this year and is awaiting extradition to the US. The No. 2 smartphone maker is accused in a separate indictment of stealing technology secrets.

The company has denied all the charges in a case that has heightened tensions over trade.
