This paper closely examines the influence of trans-migrants on the formation and development of interactions between the country of origin and the adopted country, based on the previous ethnoantropological, politicological, sociological and communicological researches. The potential of migrant activities is studied in interactions between countries, societies and cultures, as well as in the formation of national and country images. The dual identity and dual ideology of trans-migrants is viewed as an important factor for possible improvement of international relations, while avoiding unnecessary segregations and conflicts. Therefore, research of different aspects of cultural, economic and political cooperation with members of various migrant groups could lead to results that could stimulate overall improvement of international communication and other interactions, minimalising 'problematic' differences between societies. The results of the research can also be used to form a well-thought activity wich is important for an appropriate functioning in global processes. Non-existence of the activity could result in an inability of a country to successfully communicate in international relations but also with its own citizens. The aim of this work is to incite further research and discussions about the relations between the migrants, the country of origin and the adopted country, with the diaspora acting as the potential springboard for future development of international relations while applying the scientific conclusions on the creation of the national strategy in a sense of defining the international relations and the policy of identity.
