In today's world, there is a close intertwining of academic disciplines and spheres of practical interaction. To identify a potential for transfer of international practices, the authors of this study attempt to elicit cases of successful transfer of practical experience from International Relations and world politics to other fields, as well as provide illustrative examples of parallel development of similar practices. As one of the most extensive practices in the realm of International Relations, diplomacy appears to contain a large number of relevant cases. Transfer and parallel development of negotiation techniques and mediation technologies manifest themselves both in the related sphere of domestic politics and in corporate culture. Another example of business borrowing international practices is the institution of industrial espionage, which nowadays might be compared to the institution of political-military espionage in terms of its scale and organization. The study also focuses on the phenomena of parallel development of social practices, namely emancipation. While it is regarded as a process of gaining legal independence in the sphere of law, in International Relations it denotes a rejection of the idea of domination of a certain order or ideological stance. The final part of the study is dedicated to the consideration of typologies of behavior, as well as analogies and metaphors, in various social spheres. Metaphors and analogies unite such seemingly distant disciplines as International Relations and folklore studies. In addition to allusions to foreign policy events, which appear with a certain frequency in mass culture, the authors also present possible parallels between the structure of fairy tales and that of political conflict. On the grounds of the case studies, the paper highlights the diversity of areas of international engagement that have directly or indirectly contributed, or could contribute, to the emergence and/or development of other practice areas.
