In the context of globalization, migration processes have a significant impact on the formation of the modern international system. In bilateral interstate relations, the diaspora acts as a connecting link. The policy of the state of residence in relation to the diaspora can influence foreign policy decisions, and is also an indicator of the attitude towards the homeland of the diaspora. States can use the resource of the diaspora for the realization of national interests, for example, in establishing relations with foreign partners. In this case, the diaspora provides an economic, cultural and linguistic presence. The diaspora is directly involved in the life of the host society and has the opportunity to create a positive image of their homeland, the level of participation in this is not only state, but can also be of a private nature.
