The Chinese government's internal media publication system follows a strict hierarchical pattern designed to facilitate party control. A publication called Reference News—which includes translated articles from abroad as well as news and commentary by Xinhua reporters—is delivered by Xinhua personnel, rather than by the national mail system, to officials at the working level and above. A three-to-ten-page report called Internal Reference (Neibu Cankao) is distributed to officials at the ministerial level and higher.
