NEW YORK - Meng Wanzhou, a top Huawei Technologies executive detained for nearly three years in Canada, can return home to China after striking a deal with U.S. Justice Department officials in which she acknowledged helping to conceal the companys direct dealings in Iran, which violated U.S. sanctions.

The U.S. Justice Department denied politics played a role in its decision last year to open an antitrust investigation of four automakers that reached an agreement with California on fuel-efficiency standards.
