The focus of this literature review is to review and analyze how online learning promotes the development of intercultural communicative competence (ICC) in English language teaching (ELT). It aims to provide theory-based suggestions for English language (EL) teachers and researchers better to choose learning methods and activity designs for intercultural communication. It draws on the principles of Critical Interpretation Synthesis (CIS), with studies collected from systematic searches of databases supplemented by manual searches of relevant journals. The results show that with the rapid development of information technology, the popularization of network technology, and the continuous improvement of online learning platforms, online learning has become a popular learning method. Moreover, the flexibility, convenience, and interactivity of online learning provide new ways and possibilities for cultivating cross-cultural communication skills.
