How do portrayals of foreign nations as threats shape public opinion on foreign policy and domestic racial attitudes? This study examines how portrayals of China as a threat influence Americans’ support for U.S. policy toward China and attitudes toward Asian Americans. A content analysis of CNN and Fox News transcripts from 2010 to 2020 shows that both outlets increasingly portrayed China as a threat, although Fox News more often emphasized threats to the United States, whereas CNN focused more on threats affecting other countries, international institutions, and populations. A national survey and a preregistered survey experiment further demonstrate that exposure to China threat narratives, regardless of whether the threat targets the United States or another country, increases support for hawkish U.S. foreign policy and heightens anti-Asian resentment, especially among Republicans. These findings show how portrayals of foreign threats shape public opinion and spill over into racial attitudes at home.
