This paper examines the international management of human resources. People have been one of the first challenges of any company wishing to work and develop an activity in other regions. The various movements of these human resources and competencies have implicated the phenomena of culture exchange worldwide. Intercultural conflicts, intercultural competencies, and intercultural management, are topics multinational companies did not face decades ago. Researchers worked on these differences and how humans can accept and cultivate the cultural differences in society. In recent decades, the global economic scene, and more particularly the European one, has increased international competition affecting both companies with an export profile and companies targeting the domestic market. International trade is a special case in general, it has the same principles as internal trade, but it suffers from certain changes related to phenomena caused by artificial and on the other hand natural barriers such as, distance, communication and interculturalism.
