Аннотация:The article analyzes the development of the Eurasian Economic Union(EAEU) before, during and after the COVID-19 pandemic through thelens of the so-called integration dilemma, when one state perceives itsneighbors’ integration into an economic alliance as a threat to its ownsecurity or prosperity. The authors consider the processes of interstate andsupranational adaptation, as well as the adaptation of the basic model ofintegration to the existing practices of interaction as part of the project toensure four freedoms. The institutional inertia characteristic of the EAEUand the manifest desire primarily to prevent development risks are caused bythe “hybrid nature” of the integration association, in which interstate tiesand the interests of states often outweigh supranational ones. At the sametime, integration cooperation made it possible for the member states tosomewhat harmonize and coordinate their joint response to the pandemic.Sweeping anti-Russian sanctions have created new, unprecedented risksfor integration cooperation, but at the same time have opened up certainopportunities to overcome their consequences.
