This article is devoted to the problem of Russian-Lithuanian relations in the context of the Ukrainian crisis. Some tension in interstate relations arose much earlier due to certain historical events, however, its peak occurred in 2014, subsequently only overgrown with new unresolved issues. It must be said that the current situation in relations between Lithuania and Russia is not a dead end, in many areas there are obvious positive changes. Such areas are tourism, economics, culture, humanitarian ties. Along with this, one can cite as an example the field of interstate relations in which at present the dialogue between Lithuania and Russia is impossible due to foreign policy discourse, different views on universal values and geopolitical interests. The Ukrainian crisis, which began in 2013, became a catalyst in the termination of political relations between Lithuania and Russia. Until 2013, the politicians of these states made attempts to establish a dialogue, albeit not striving for friendly relations, a priori impossible due to historical narrative, but at least rational and mutually beneficial, then after the annexation of Crimea all efforts were completely stopped. Moreover, information confrontation intensified. The article discusses in detail the positions of states on the events of the Ukrainian crisis and the specific reasons that caused such a rapidly growing mutual hostility.
