Abstract: 　It is of great significance to analyze the characteristics of China-related reports of international online media during the pandemic of COVID-19 in China, which will help the government accurately study and judge the international public opinion environment, respond effectively, and maintain the image of the country.This paper uses statistical analysis, sentiment classification, and topic models to perform trend analysis, source analysis and content analysis on the text of the GDELT COVID-19 database. Correlation analysis is used to explore factors related to the number of China-related reports in various countries, and hierarchical clustering clusters countries with similar report characteristics. The study found that international media reports on China are mainly dominated by Western countries led by the United States, and the reports are significantly unbalanced; Negative China-related reports are mainly exported by the United Kingdom and the United States; The greater the proportion of import and exports to China in its total import and exports, the more concerned it is about China’s covid-19 epidemic; The countries with higher medical standards, their China-related COVID-19 epidemic reports account for the proportion of all reports in the country, which is lower than the average level. This paper systematically explains the characteristics of China-related reports by international media in current public health emergencies, and provides some references for the government to effectively respond to international public opinion.
