International students studying and living in a foreign context often complain about difficulties establishing friendships with host nationals. This study investigates host country nationals' (HCNs) willingness to develop intercultural friendships with international students who are sojourning in China by exploring the effects of face-to-face and online intergroup contact, HCNs' attitudes, intercultural communication competence (ICC), and perceived intergroup threats. Survey data from 469 HCNs indicate that (a) face-to-face and online contact are indirectly and positively related to their willingness to form intercultural friendships, (b) face-to-face contact can moderate the relationships of online contact with HCNs' intergroup attitudes and perceived intergroup threats, and (c) both ICC and intergroup attitudes can positively predict friendship formation whereas perceived intergroup threats act as a negative predictor. The implications of our findings for future research and practice are presented.
