This is a case study of the College of Foreign Economic Relations (COFER) (Ho Chi Minh City, Vietnam) with six Business English teachers as participants. The study was done to explore the teachers' perceptions of teaching Intercultural Communicative Competence (ICC) to the Business English students through their understanding of ICC and ICC teaching practices. The data were collected via classroom observations, in-depth interviews, and analyses of syllabi, lesson plans and two Business English textbooks in current use. Inductive analysis was used to analyze the data. The findings revealed that the teachers did not perceive ICC adequately and neither did they teach ICC sufficiently in spite of acknowledging the importance of ICC in Business communication. The study not only enabled Business English teachers to gain a deeper insight into all the aspects of ICC but also provided educators with a good source of data for more efficient policies to develop ICC teaching in Business English education.
