International collaborations in the vocational and training (VET) sector have grown significantly in the past three decades in China as well as in other parts of the world. Despite its growing prominence, it remains a largely under-researched field compared to the large volume of research on universities' internationalization. In particular, it is unclear how internationalization practices improve vocational students' academic and social competencies and readiness for employment. This case study was intended to fill this current gap in the literature by investigating a selected joint venture VET college in China. This study employed a wealth of data as evidence that international programmes could benefit vocational students in their English skills, professional knowledge, intercultural competence, and personal and career development. In additional to the opportunities created for vocational students, international programmes are expected to offer workplace experience and design a curriculum that suits students with different future plans. The findings of this study indicate that international collaborations in the VET sector have the potential not only to better prepare vocational students for life and employment, but also to address the challenges facing the VET system in developing economies.
