Introduction. In November of 1921 after the meeting between Mongolian officials and Vladimir Lenin, an Agreement on Friendly Relations between the two states was concluded. This significant act confirmed the mutual recognition of the only legitimate government by both counterparties, measures of prevention of unfriendly actions by third parties, exchange of plenipotentiary representatives and ambassadors, state border regulations and the most favorable nation treatment for citizens whilst visiting the counterparty and jurisdiction. It also provided the regulations for a number of trade matters, intercommunication issues, questions of personal property etc., however, in actuality this document touched upon a smaller realm of mutual relations that had already been established before the execution of the Agreement, having been formalized in other documents, such as letters and memorandums. These precontractual acts are of genuine interest not only due to their uncertain legal nature and consequences, but also because they cover a much wider range of collaboration and cooperation issues than the Agreement dated November 5, 1921. Goals. So, the paper attempts an interdisciplinary insight into the mentioned documents (addresses, diplomatic notes, letters, etc.) to have preceded the Agreement and formalized Soviet Russia's foreign policy in the region and its presence in the territory of Outer Mongolia - to determine the role and impact of the former. Materials and Methods. The study focuses on widely known materials contained in diverse published collections of documents from the Soviet era that were never viewed by most researchers as important tools to have guaranteed the national interests in the Far East. To facilitate a more comfortable perception of the investigated materials by different specialists, the paper was divided in two - Part One to focus on research tools and its ideological essentials, and Part Two to emphasize certain instruments to have secured the 'export of revolution'. Results. The article specifies four key lines of cooperation: 1) bilateral collaboration that includes 'export of ideology' and sufficient tools thereto, such as disassociation from former political regimes, support for anticolonial sentiments, securement of equal rights in foreign policy issues, cooperative struggle against the common ideological enemy - world capitalism, 'soft power' in the form of educational projects; 2) security arrangements for Soviet territories and borders, including assistance to Mongolian comrades in their fight against the White Guard, allocation of the Red Army units within Mongolian territories until the complete eradication of the White threat, with the participation of military units from the Far Eastern Republic; 3) economic cooperation through mutual financial and economic support of industrial construction projects, resource development and social infrastructure initiatives, etc., 4) joint actions on the international stage pinnacled with the recognition of the Mongolian People's Republic by China (1945) and the rest of the world community (1961). This shows that during the shaping of the political agenda towards Mongolia the then Soviet leaders did not view contractual aspects of the mechanism as fundamental, and attached no paramount importance to international agreements, which had been distinctive of the Russian Empire.
