China is using part of its internal internet surveillance network to mine data from Western social media and provide its government agents with information on foreign targets, The Washington Post reported on Friday.

Reviewing hundreds of Chinese bidding documents, contracts and company filings, the Post reported that China's public opinion analysis software - used to detect politically sensitive information online - was also being used to collect information on foreign targets through U.S. companies like Twitter and Facebook.
