The article analyzes the system of relations between the European Union, the Eurasian Economic Union and China in the light of the implementation of the Chinese project "One Belt - One Road". The prospects for its implementation, the associated difficulties and risks for Western Europe and Russia are described. Today, in the space of Greater Eurasia, which includes Western Europe, three integration mega projects have formed in varying degrees of maturity - "One Belt - One Road", vigorously promoted by China, has been added to the European Union and the Eurasian Economic Union. In this regard, experts discuss many questions: is it possible to combine these three projects; if so, what difficulties and obstacles may arise along the way; what are the prospects for the "triangle", historically unprecedented in its scale and, possibly, economic and geopolitical significance in the future? Analysis of this entire range of issues today is a complex scientific task.
