Globally, organizations are increasingly embracing corporate social responsibility (CSR) to strengthen competitive advantage. Although CSR is recognized to be context-sensitive, the literature is still lacking studies that examine CSR in different contexts, particularly non-western ones. Our study adds to a deeper understanding of CSR in Vietnam by identifying the predictors of CSR attitudes of business students. Vietnam has rich cultural, social, and economic characteristics that offer new theoretical perspectives and insights on the contextual nature of CSR. Our findings showed that CSR attitudes related positively to idealism and student seniority, and negatively to materialism and male students. A positive CSR–relativism relationship was uncovered. Spirituality related positively to the importance of CSR to business sustainability and negatively to CSR's importance to short-term competitiveness. The findings have theoretical and practical implications on the understanding and practice of CSR that would benefit CSR researchers, business organizations, and education institutions.
