In August, foreign ministers from 10 nations blasted China for building artificial islands in the disputed South China Sea. As media around the world covered the diplomatic clash, a radio station that serves the most powerful city in America had a distinctive take on the news.

Located outside Washington, D.C., WCRW radio made no mention of China's provocative island project. Instead, an analyst explained that tensions in the region owed to unnamed "external forces" trying "to insert themselves into this part of the world using false claims."

Behind WCRW's coverage is a fact that's never broadcast: The Chinese government controls much of what airs on the station, which can be heard on Capitol Hill and at the White House.
