Facebook acknowledged Tuesday that it has shared “controlled” access to user data with at least four Chinese companies, including one flagged as a national security threat, a report said.
The social media giant approved data access to Chinese firms Lenovo, Oppo, TCL and Huawei—an electronics manufacturing company with close ties to China’s government—in agreements which date back to at least 2010, The New York Times reported.
The paper recently 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.
“I look forward to learning more about how Facebook ensured that information about their users was not sent to Chinese servers,” said Sen. Mark Warner, D-Va., vice chairman of the Senate Intelligence Committee.
Facebook, which has been banned in China since 2009, issued a statement ensuring that access to all information shared with Huawei was carefully managed and stayed on its phones, not on Huawei’s servers.
The company said it would end its data partnership with Huawei by the end of this week, Reuters reported. It is also ending partnerships with the three other Chinese firms.
“Facebook is learning hard lessons that meaningful transparency is a high standard to meet,” said Sen. John Thune, R-S.D., chairman of the Senate Commerce Committee.
The Federal Trade Commission is currently investigating Facebook to determine whether the company adhered to the 2011 settlement requiring it to enact a number of security measures to ensure users’ information isn’t shared without their consent.
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 risks—though the company has long denied such concerns.
For years, Huawei and its Shenzhen-based rival ZTE have been the subject of security misgivings in the U.S., but they have come under particular scrutiny since the start of the Trump administration. The Pentagon in May banned the sale of Huawei and ZTE phones on military bases, four months after AT&T dropped a deal to sell a new Huawei smartphone.
