Cross-border partnerships are increasingly important for higher education in the twenty-first century. Drawing from the business sector's resource-based theory, this paper explores international partner selection among higher education institutions in Hong Kong, Singapore and Japan. According to resource-based theory, institutions may seek partners with specific technical capabilities, managerial capabilities or other intangible resources to access external knowledge and capabilities, develop internal resources and gain competitive advantage. Through document analysis and interviews, this investigation identified twelve attributes that influenced international partner selection for higher education institutions in these contexts. Eleven fit within resource-based theory's criteria areas of technical capabilities, managerial capabilities and intangible resources. These determined the attractiveness of potential partners. However, existing relationships, the twelfth attribute, was often the deciding factor of whether or not a partnership would move forward. Importantly, while contextual differences were observed, these attributes were present across contexts.
