China's State Council Information Office, which handles media queries on behalf of the Chinese government, including on personnel matters, did not immediately respond to a request for comment and Reuters was unable to obtain Feng's contact details to reach him for comment.
The five sources said Feng's removal was linked to rules the NPPA announced last month that sent stocks in the world's largest video games sector, including industry giant Tencent
(0700.HK), plunging.
The sources declined to be identified as authorities had yet to officially announce Feng's departure.
