AKIPRESS.COM - Facebook has confirmed it has a data-sharing partnership with Chinese firms including Huawei, a company US intelligence previously flagged as a security threat, BBC reported.

The agreements gave the Chinese firms some access to users' data to help them build Facebook "experiences" on their own platforms.

Facebook said all the data collected remained on users' phones not servers.

The company is already under scrutiny over how it uses members' information.

Facebook has been blocked in China since 2009 but the company has been trying to find other ways to access the massive potential market.
