Over a considerable period of time, China has formulated a series of press freedom principles and guidelines for practice. These have their own distinctive features. China has also established its own legal system to regulate press freedom. By using the methods of literature analysis, text analysis, historical analysis and induction methods, this paper studies the origin, spiritual essence and core content of China’s press freedom. In addition, the current general framework and functions of China’s press laws, as well as the significance of press legislation, are discussed. The study finds that although China has established a relatively complete legal framework to govern the press, but with the rapid development of China’s social economy, the problems facing news dissemination will be more and more, the promulgation of specialized laws remains necessary and inevitable in the realization of the supervision of the press control. China needs to establish a perfect news law as soon as possible.
