This paper explores the ideological positions of two leading Korean newspapers, Chosun Ilbo and Hankyoreh Shinmun. With the framework of Critical Discourse Analysis(CDA), editorials about MERS were analysed in this paper. CDA is a type of discourse analytical research that primarily studies the way social power abuse, dominance, and inequality are enacted, reproduced, and resisted by text and talk in the social and political context. With such dissident research, critical discourse analysts take explicit position, and thus want to understand, expose, and ultimately resist social inequality(van Dijk, 2001). As a result, each newspaper can shows that the positive information of actor to support our ideology can be expressed and emphasized, the negative information can be suppressed and de-emphasized. It can also say that the positive information of actor to oppose our ideology can be suppressed and de-emphasized, the negative information can be expressed and emphasized. Each newspaper’s values to pursue can be confirmed, either. The values are reproduced and spread constantly through editorials.
