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. The data included work history, relationship status and likes on device users and their friends.

The Times reported the recipients of Facebook data included Chinese firms like Huawei that have been banned by some U.S. government agencies due to security concerns. Facebook told the newspaper it would end its data partnership with Huawei by the end of this week.
