In response to a new strategy that puts expanding global relations at the top of the university's priorities, PSUT's International Relations Unit (IRU) was founded. The goal of this strategy is to build institutional capacity and a culture of internationalization through the exchange of knowledge and best practices. This resulted from the understanding that all of the diverse university portfolios are impacted by internationalization.

The International Relations Unit is responsible for managing the university's agreements, endowments, study abroad and academic exchange programs, mobility scholarships, and services for overseas students and scholars.
