In June 8th, Beijing time, a senior U.S. senator said on Thursday that he had asked Google parent company Alphabet and Twitter to submit information on data sharing agreements with Chinese manufacturers. Prior to this, Facebook has disclosed similar cooperation with several Chinese companies this week.
Facebook said on Tuesday that the company signed at least 4 cooperation agreements with Chinese companies.
Alphabet announced its strategic cooperation with HUAWEI, millet and Tencent.
Twitter refused to comment on it. The New York Times reported last Sunday that Facebook's user friend data can be used by device makers without the user's explicit permission. Facebook denied the case and said that data access allows users to use account functions on mobile devices.
