Intercultural competence has become one of the important goals of foreign language education. The potential and value of foreign language education on students' intercultural competence (IC) has been widely recognized by academia. Currently, most of the research on intercultural foreign language teachers in China focuses on university teachers, with little attention paid to primary school EFL teachers. However, the cultivation of IC is a staged and continuous process which cannot be achieved in one stroke. Therefore, it is necessary to include primary school EFL teachers in the study of IC cultivation. This paper presents data on Chinese primary school EFL teachers' beliefs about incorporating IC into foreign language teaching. Specifically, their understanding of culture, IC, and intercultural teaching practices are investigated through interviews. The interview transcriptions were analyzed using thematic analysis. The research found: 1. Chinese primary school EFL teachers generally hold an essentialist view of culture; 2. Teachers emphasize the attitudinal dimension of IC; however, they also exhibit a tendency to oversimplify IC or perceive it as a higher-order skill than language proficiency, hence deeming it unsuitable for cultivation at the primary school level; 3. Most cultural teaching practices are teacher-centered, focusing on background knowledge-style introduction. In general, teachers’ intercultural teaching practices align with their cultural outlook. At last, the study explores two suggestions for promoting intercultural foreign language teaching: 1. Supporting primary school EFL teachers in updating their language and culture concepts system; 2. Encouraging teachers to reflect on their daily teaching practices as a major opportunity to promote the development of intercultural foreign language teaching.
