U.S. prosecutors are investigating whether Chinese tech giant Huawei stole trade secrets from U.S. companies, the Wall Street Journal reports.
The newspaper says investigators are looking into whether the company stole technology behind a robotic device that T-Mobile used to test smartphones.
The Journal report Wednesday cites several people familiar with the matter who are not identified by name.
The Justice Department declined to comment.
Huawei executive Meng Wanzhou was arrested in Canada last month. The U.S. is seeking to extradite her to face charges she misled banks about the company’s business dealings in Iran.
