Historically, journalism ethics has been parochial with its standards applying to particular groups or regions. The globalization of information raised with new media technologies can enable a country's media coverage to be quickly integrated into the complex network of global political and cultural interactions via the Internet. With global reach comes global responsibilities, journalism ethics need to be transformed from the previous regional media ethics based on print and broadcasting to a global journalism ethics derived by the new communication technologies. Under the age of COVID-19 pandemic, restructuring of the global economy and emergence of deglobalization is a fact, the rise of populism and nationalism challenges the impartiality and objectivity in journalism. The globe is connected electronically and collided perspectively never like before. In such a climate, the role of media constitution and the need for global journalism ethics is due not only the technological innovation; it is due to the changes in the world that public inhabits: global crises such as the ecological deterioration, the wide gap between the rich and the poor, the ravages of infectious diseases have become problems that are difficult for individual countries or nations to solve, and mankind has formed a community of linked destinies and shared futures. Biased and parochial journalism can wreak havoc in a tightly linked global world.

This paper examines the coverage of “2020 Wuhan Lockdown” in American and Chinese mainstream media in both U.S. (The Associated Press) and China (XINHUANET). Based on framing theory, distinct character and differed news disclosure was founded in these reports. In this case, the traditional media in China intended for social stability massively use constructive disclosure, while the U.S. media focused on the damage to Wuhan citizens and emphasis the spectacle of disaster rendered in the perspective of the “Other”. Cosmopolitan ethics asserts the equal valve and dignity of all mankind.
