The rise of the internationalised business environment and the intensification of global competition have led to an increasing number of people travelling across cultural and linguistic boundaries. As a result, dealing with the full complexity of ethnic diversity has become a daily task for a substantial part of the business community, as well as other parts of society. Due to this recent development, the understanding of intercultural communication has gained importance in utilising advantages connected to doing business in diverse environments. By drawing on anthropological theories on ethnicity and ethnic identity this book argues that the relation between language, learning, and ethnic identity is a dynamic and dialectical process of intercultural interaction and negotiation.
