The tutorial discusses the main theoretical problems of intercultural communication. Examples of interaction between representatives of different cultures are given, the features of communicative behavior of different peoples are revealed. In contrast to the existing manuals in this discipline, the proposed textbook considers not only the cultural aspects of intercultural interaction, but also linguistic (theory of speech activity, model of speech communication), psycholinguistic (image of the world, linguistic consciousness), ethnological (ethnos as a socio-cultural reality), as well as ethnopsychological (tolerance as a condition and result of effective intercultural communication).
