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