WASHINGTON - Facebook Inc said Tuesday it has data sharing partnerships with at least four Chinese companies including Huawei, the world's third largest smartphone maker, which has come under scrutiny from U.S. intelligence agencies on security concerns.The social media company said Huawei, computer maker Lenovo Group, and smartphone makers OPPO and TCL Corp were among about 60 companies worldwide that received access to some user data after they signed contracts to re-create Facebook-like experiences for their users.Members of Congress raised concerns after The New York Times reported on the practice on Sunday, saying that data of users' friends could have been accessed without their explicit consent. Facebook denied that and said the data access was to allow its users to access account features on mobile devices.More than half of the partnerships have already been wound down, Facebook said. It said on Tuesday it would end the Huawei agreement later this week. It is ending the other three partnerships with Chinese firms as well.Chinese telecommunications companies have come under scrutiny from U.S. intelligence officials who argue they provide an opportunity for foreign espionage and threaten critical U.S. infrastructure, something the Chinese have consistently denied.Senator Mark Warner, vice chairman of the Intelligence Committee, who asked Facebook if Huawei was among the companies that received user data, said in a statement that the House of Representatives Intelligence Committee had raised concerns about Huawei dating back in 2012."The news that Facebook provided privileged access to Facebook’s API to Chinese device makers like Huawei and TCL raises legitimate concerns, and I look forward to learning more about how Facebook ensured that information about their users was not sent to Chinese servers," Warner said.API, or application program interface, essentially specifies how software components should interact.A Facebook executive said the company had carefully managed the access it gave to the Chinese companies."Facebook along with many other U.S. tech companies have worked with them and other Chinese manufacturers to integrate their services onto these phones," Francisco Varela, vice president of mobile partnerships for Facebook, said in a statement. "Facebook's integrations with Huawei, Lenovo, OPPO and TCL were controlled from the get-go — and we approved the Facebook experiences these companies built."Varela added that "given the interest from Congress, we wanted to make clear that all the information from these integrations with Huawei was stored on the device, not on Huawei's servers."
