Recognizing the globalization of higher education institutions, this study examined the influence of university–student relationships on host country-related outcomes, including student attitudes, purchase intentions, and policy support. A survey was conducted with Chinese students who had studied or who were currently studying at South Korean universities. Its results showed a significant positive association between Chinese student perceptions of their relationships with host universities and their attitudes toward South Korea. In addition, their positive attitudes led to (i) intentions to purchase Korean products and (ii) policy support for the Korean government. The theoretical and practical implications of study findings are discussed from the perspectives of public diplomacy and the university’s role in a highly globalized education system.
