The FBI is examining exiled Chinese businessman Guo Wengui and the money used to fund his media efforts in the U.S., including his work with Steve Bannon, a former senior adviser to President Trump, according to people familiar with the matter.

Federal Bureau of Investigation national security agents in recent months have asked people who know both men for information on Mr. Guo’s activities, including the source of funds of a media company linked to him that hired Mr. Bannon in 2018 as a consultant, the people said…

“Mr. Bannon and Mr. Guo have worked together on fighting the [Chinese Communist Party] and also on setting up a media and technology distribution platform that breaks through the firewall directly to the Chinese people in China and across the globe,” the person said…

The Wall Street Journal couldn’t determine the source of funds used to pay Mr. Bannon. But Mr. Guo has in the past used what appeared to be a third party to provide funds to a contractor. He said in a court filing that a Hong Kong company, ACA Capital, paid a $1 million deposit on separate work he commissioned from a research firm, Virginia-based Strategic Vision. At the time of the payment in January 2018, ACA Capital was owned by a man named William Je, Hong Kong corporate records show.
