Based on reports on China’s COVID-19 Pandemic corpus and through meticulous combing and mining subject words, inquiry collocation network and concordance lines, it is found that topic features of the coverage focus on diplomacy, media/propaganda, leaders/officials to construct Chinese national image and set the agenda. The Economist distorted China as “silencing” at home, “beautifying” the results of the fight against the epidemic through publicity, “aggressively confronting” with the outside world (especially the United States), actively raising its voice in the field of international public opinion to enhance its international image, and trying to “occupy the high position of global leadership” during the pandemic. Most of the reports and narratives of The Economist showed obvious negative semantic rhymes and biased stances, and repeatedly emphasized the difference between Chinese and Western political ideologies, politicizing the epidemic. In this case, Chinese discourse strategies and ways of expression can be chosen to reconstruct national image and promote international discourse power.
