Knowledge of foreign languages and intercultural skills are the first challenges that need to be faced in the world of international business. In international companies, one of the questions raised is as to whether a uniform business language should be adopted, as well as to how the use of various foreign languages affects day-to-day business. Topics to be presented and discussed will include: new methods of intercultural language training, the challenges of cross-border cooperation (e.g. in virtual teams), the prospects for international mobility and intercultural team management.
