Previous studies proposed an effective model to examine media's behaviour in conflict reporting--war and peace journalism paradigm, which consists of a series of dimensions to analyze news coverage. It indicated that media using more war journalism would escalate the conflicts and the media using more peace journalism would reduce the conflicts. This paper mainly combs the relevant research on War and Peace Journalism Paradigm, as well as the comparative research of different media systems, with particular attention to the media reports of China and the United States. Based on this review, a new research will be devoted to summarizing the comparison of different media systems, the dynamics of war and Peace News models and their performance in different political backgrounds, as well as the news reporting models and their impact on the countries of origin and response. At the same time, the study will also predict the correlation between the performance of different media and the change of public opinion on both sides.
