Intercultural competence is a range of cognitive, affective, and behavioural skills that lead to communicate effectively and appropriately with people of other cultures. Effective intercultural communication relates to behaviors that culminate with the accomplishment of the desired goals of the interaction and all parties involved in the situation. Appropriate intercultural communication includes behaviors that suit the expectations of a specific culture, the characteristics of the situation, and the level of the relationship between the parties involved in the situation.
