When we talk about migration in Europe, generally people talk about two different flows: illegal immigration flows from third world countries (Middle East, Asia, Africa) // infra migration flows from Eastern to Western Europe. This infra migration flow produces both opportunities and challenges for European countries. In time of Covid-19, one challenge is very much visible: the lack of workforce in health systems. Other challenges exist such as emigration of youth (the most dynamic and innovative part of the society), decline of population or quest for identity, etc. Europe should be a place of permanent interactions and exchanges. Consequently, East-West migration flows cannot be excessively asymmetrical compare to West-East migration flows as it will produce important disequilibrium. To counter the problems of emigration in Central and Eastern Europe, West-East migration has to be stimulated. Ukraine as an important emigration country is an interesting example and the project will focus on how to improve Ukraine’s attractiveness in order to stimulate the arrival of Western Europe’s citizens. In this case two types of public can be targeted: Ukrainian diasporas (both Ukrainians and bi-nationals) living in Western European countries who plan to come back to their home country and Western European youth looking for professional challenges. Our study will focus on four countries: France, Germany, Poland and Ukraine. The objectives of this project are to improve Ukraine’s attractiveness in Western Europe (providing recommendations to key stakeholders) and to stimulate Western European countries’ migration flows towards Ukraine. Obviously, in parallel, the project will aim to Strengthen links and networks between Ukraine and Western European countries (France, Germany and Poland).
