Abstract. The concept of “Greater Eurasia” includes a certain area of international cooperation on the Eurasian continent.Filling it with specific projects and creating international institutions for this purpose depends on the will and interests of participating countries. The Eurasian integration is an integral part of an emerging Great Eurasian Partnership. To assess the Eurasian integration process the concept of “economic connectivity” is used which refers to the level of interaction  between economies of integrating countries in institutional, trade, economic and social aspects. More than 90% of  the EAEU foreign trade with third countries is with the states of Eurasia. From the point of view of the development of national economies different levels of regionalization processes complement each other. Therefore the desire to develop the Eurasian integration “in breadth” and “in depth” is quite natural. Prospects of the Eurasian integration are closely related to the development of cooperation in the framework of Greater Eurasia. But the dynamically developing Eurasian integration will allow individual countries and the entire Union to participate more effectively in the Great Eurasian Partnership.
