Chinese tech giant Huawei pleaded not guilty to charges Thursday in New York. The company is charged with violating U.S. sanctions on Iran and obstruction of justice.
The U.S. is accusing Huawei's CFO, Meng Wanzhou, of covering up the alleged sanctions violations. Canadian authorities arrested her in Vancouver in December and she is currently facing possible extradition to the U.S.
The company also pleaded not guilty to other charges in Seattle. It is accused of stealing trade secrets from T-Mobile.
U.S. officials have said the company's devices pose a national security threat and have warned allies about the tech giant. In August, President Donald Trump signed the National Defense Authorization Act which bans federal agencies from purchasing or using Huawei's products. Now, the company is suing the U.S. government and is asking a federal court to overturn part of the act.
The company will appear in a New York court on April 4.
