MENLO PARK, Calif. (AP) — Facebook has acknowledged it shared user data with several Chinese handset manufacturers, including Huawei, a company flagged by U.S. intelligence officials as a national security threat, as it faces a fresh wave of allegations over its handling of private data. Chinese firms Huawei, Lenovo, Oppo and TCL were among numerous handset makers that were given access to Facebook data in a "controlled" way approved by Facebook, the social media giant's vice president of mobile partnerships, Francisco Varela, said in a statement on Tuesday. The statement came after The New York Times published reports detailing how Facebook has given device makers deep access to the data of users' friends without their explicit consent.
