Air Pollution Coverage, Anti-Chinese Sentiment, and Attitudes towards Foreign Policy in South Korea

Abstract

Air pollutants allegedly originating from China have become a thorny issue in South Korea. Despite a neutral view of the topic on the part of the South Korean government, recent public polls show a high correlation between the air pollution issue and negative sentiment toward China. How has the media reported on China regarding air pollutants in South Korea? What is the effect of media reports on air pollution on anti-Chinese sentiment and foreign policy attitudes? By examining news headlines and Twitter data in 2015 and 2018, this work finds that media reports blaming China for air pollution doubled during the 2015–2018 period. Discourse surrounding air pollution also shifted: negative sentiment directed at both the Chinese government and the Chinese people increased in 2018 compared to 2015. In addition, an original online survey experiment shows that China-blaming articles have a causal effect on increasing related resentment, particularly toward Chinese people, and that this effect is moderated by age group. Such articles have also had negative effects on foreign policy attitudes via increased anti-Chinese sentiment; greater hostility toward the Chinese people is found to have a causal effect on reduced support for strengthening relations with their country.
