Internationalization in higher education and the promotion of intercultural interaction are becoming increasingly prevalent globally. Conducted in Hong Kong, this mixed-methods study investigated one facet of these initiatives, namely intercultural activities on campus. Both home (n = 305) and international (n = 127) students' awareness of, attitudes toward, and participation in these activities were examined. The results showed that these three variables were significantly inter-correlated, and awareness and attitude together explained 36% of the variance in participation. While both groups had similar levels of awareness and participation, the international students were slightly more positive toward these activities than the home students were. Lack of time, absence of company, and uninteresting activities were found to be the top three reasons for low/no participation. Follow-up semi-structured interviews were conducted with 18 participants, who elaborated on awareness-raising promotion platforms for these activities, motivators, and demotivators for participation, and the general differences between home and international students. The article ends with a discussion on these findings.
