Economic relations between Russia, Mongolia and China were mainly constructed to connect the Chinese Silk Road Economic Belt, the Russian Eurasian Economic Union, and Mongolia's proposed «Prairie Road», aiming to encourage the three parties to reach their tourism resource potentials, take international cooperative advantages, expand economic development space, and raise the joint competitiveness of the nations involved in the international tourism market. The authors justify why Mongolia plays and could play, an even more vital role in the economic relations between both Russia and China, pointing out key problems that Mongolia faces, being the least economically independent country, as they try to be more active with their involvement in the discussions of these political policies. Also authors pointed out the need for Mongolia to seek further assistance West, in terms of alliance, to balance the already increased Chinese influence in the region. In conclusion, the future of this trilateral economic trade corridor will be one needing careful orchestration and cooperation under the proposed “One Belt-One Road” initiative ensuring its effectiveness. This will be subject on decisions made in the future.
