This paper reviews the body of research on intercultural awareness and its growing importance in the English language teaching profession. Rooted in the well-established concept of cultural awareness in language teaching, intercultural awareness represents a more embracing view of culture that captures its emergent and dynamic nature in the relationship with language. The types of knowledge, skills and attitudes of intercultural awareness are briefly presented with general suggestions and guidelines for application in the English language classroom. Finally, these theoretical developments are discussed with reflections and implications in the Vietnamese context.
