Since at least 2016, U.S. authorities have been probing Huawei's alleged shipping of U.S.-origin products to Iran and other countries in violation of U.S. export and sanctions laws, two of the sources said.

News of the Justice Department probe follows a series of U.S. actions aimed at stopping or reducing access by Huawei and Chinese smartphone maker ZTE Corp to the U.S. economy amid allegations the companies could be using their technology to spy on Americans.
