In May 2019 we will celebrate the fifth anniversary of the signing of the Treaty on the Eurasian Economic Union (EAEU) and the 25th anniversary of the idea of modern Eurasian integration. Since then, the Eurasian Economic Union established itself as a quite successfully developing, open and attractive integration block, which has indeed become the indisputable reality of the economic processes in Eurasia. Perhaps enough time has passed so that we might begin to think about a “theory of Eurasian integration” in itself, as well as to outline its potential contents.
