This study examined the news coverage of the August 2020 Chinese People’s Liberation Army (PLA) military exercise against Taiwan in order to investigate the content discrepancies, attitudes, and political leanings of the four mainstream media outlets in Taiwan regarding cross-strait conflict issues. Using the theories of war/peace journalism framework and patriotism framework, the study analyzed and compared the choices of news sources, the uses of keywords, and the portrayals of events among different media. Quantitative findings reveal that there were significant differences in the coverage of four different media in Taiwan in terms of the expressions of favorability towards the home country or the adversary in international conflicts, the positions adopted in reporting on whether Taiwan and the United States can deter the Chinese Communist Party’s (CCP) military aggression against Taiwan, and the uses of reporting frameworks. No significant differences were found in terms of choices of news sources and the number of news items. The findings indicate that the China Times tended to use peace journalism frameworks. The Liberty Times and the Apple Daily leaned towards war journalism frameworks and patriotism framework, tended to express negative sentiments towards the Chinese government, and believed that China cannot successfully invade Taiwan by force. The United Daily News, in comparison, maintained a relatively neutral stance. Qualitative analysis and discussion were included to interpret the findings at the end of the study, as well as the limitations of the study and suggestions for future study.
