This article analyzes the development potential of Greater Eurasia and its long-term institutionalization. The authors believe that Greater Eurasia, as a geopo-litical reality, is undergoing a certain transformation. Originally formed as a pole of confrontation under the pressure of American politics and based mainly on the Russian-Chinese strategic partnership, now it is acquiring more and more features of the international community, in which the development agenda pre-vails. This so far only emerging international community is involving more and more players, expanding its geographic coverage almost throughout the Eura-sian continent, which poses new challenges for its participants: overcoming geo-political contradictions, forming a sustainable security architecture and linking potentials for achieving economic growth. The approaches and motives of the main Eurasian powers and the possibilities of their linking in order to build a geopolitically sustainable international community “from Lisbon to Singapore” are examined. This text develops and completes some of the theses presented by the au-thors in the article “From Greater Europe to Greater Eurasia: what brings the world a fundamental geopolitical shift”, which was published in the previous issue of the journal “Vostok (Oriens)”.
