This article takes all the China-related reports in Vietnam’s Nhan Dan from 2016 to 2020 as the research object, and discusses the national image of China constructed by Vietnam’s mainstream media from the aspects of the number of reports and the content of reports around the news theme. The study found that Nhan Dan gave China all-round attention, and reported extensively on key issues and social life related to China’s politics, economy, and military affairs. The positive and negative images of China’s national image presented in the reports coexist. The reports reflect the attitude of Nhan Dan as a mainstream media in Vietnam. The reports not only emphasize China’s important position in international affairs, but also hold an attitude of risk awareness and threat vigilance.
