Abstract
The article examines the economic cooperation between Kazakhstan and Russia during the first decade of the Eurasian Economic Union's existence in its main spheres - mutual trade and investment. It analyses the state and trends in trade turnover, exports and imports, gross and net inflow of direct investment, as well as investment position. In addition, the situation change in the sphere of functioning of enterprises in Kazakhstan with the participation of the Russian capital is considered. All the considered parameters of bilateral cooperation are considered in comparison with more general indicators of Kazakhstan's foreign economic activity to improve the objectivity of assessments of the available progress and to identify leading or lagging areas of cooperation. Advanced dynamics characterize the revealed trends in the development of bilateral cooperation in most of the considered spheres, which allows us to conclude the positive impact of membership in the EAEU on the realization of the potential of economic cooperation between the two countries.
