US Federal prosecutors have added new charges against Huawei, its U.S. subsidiaries and the chief financial officer. The charges include racketeering and conspiracy to steal trade secrets from U.S.-based companies. Huawei is also accused of doing business in countries subject to U.S. sanctions such as North Korea and Iran. Prosecutors accuse Huawei of helping Iran's government "by installing surveillance equipment, including surveillance equipment used to monitor, identify and detain protesters during the anti government demonstrations of 2009 in Tehran, Iran." The indictment also states that for decades, Huawei has worked to "misappropriate intellectual property, including from six U.S. technology companies, in an effort to grow and operate Huawei's business." According to NPR, Huawei and its subsidiaries allegedly attempted to recruit employees from rival companies or would use proxies such as professors working at research institutions to access intellectual property.
