Wong, Ho ChunThis dissertation investigates how a global shock such as the COVID-19 pandemic creates challenges and opportunities for the projection of strategic narratives. Sitting on the intersection of the literature between journalism studies, political communication, and international relations, the strategic narratives framework provides a comprehensive approach to evaluate the stories told by political actors that are aimed at influencing perceptions. The author proposed a narrative-centric perspective to enrich the theoretical framework. While the conventional policy-centric perspective evaluates strategic narratives as a means to legitimize political behaviors, the narrative-centric perspective considers strategic narratives as tools for shaping the identities and characterization of political actors. A global crisis such as the COVID-19 pandemic presented an opportunity to frame pandemic responses in service of strategic goals. While political actors could legitimize policies in the name of health amid the lack of scientific authority in the infodemic where problematic information overwhelmed the global information environment, the situation also enabled political actors to frame policies such as travel restrictions for enhancing or renegotiating actor identities and worldviews. This dissertation analyzes the projection of COVID-19 strategic narratives and how they responded to foreign strategic narratives in the U.S. and Chinese English-language national news. A large sample of online news (N = 263,014) was sampled from the GDELT Coronavirus news dataset (The GDELT Project, 2020). This dissertation employed mixed methods of human-in-the-loop machine learning, conventional content analysis, and Granger causality tests to identify and examine strategic narratives, as well as evaluate the interactions between strategic narratives. Findings suggest that Chinese strategic narratives were responsive to offensive strategic narratives from the U.S. and depicted the U.S. as an immoral actor who intentionally smeared China. The U.S. reinforced the identity-level strategic narrative that China lacks transparency through issue-level strategic narratives about travel policies and virus origin. Two patterns of strategic narratives projection were found. Chinese strategic narratives maintained coherent storylines in the three years and between news outlets. They projected a clear Chinese story to the international audience but found it difficult to address the rapid changes in pandemic situations and policies. Meanwhile, strategic narratives from the U.S. were less coherent and were contested domestically between news outlets. Although it might have weakened a unified U.S. story, the flexibility allowed strategic narratives to transform and adapt to evolving pandemic realities. U.S. strategic narratives were able to frame stories about travel restrictions and virus origin as a manifestation of the lack of transparency from China. This dissertation demonstrated the feasibility of studying the dynamics of strategic narratives through a large dataset. The mixed method approach offered a thick analysis of strategic narratives and illustrated their interactions, thus consolidating the theoretical and methodological foundation for future research on strategic narratives contests.enDissertationJournalismInternational relationsCommunicationChinaFramingHealth communicationInternational newsNarrativesPolitical communication
