The article analyses discursive and practical activities by governmental and non-governmental actors in Russia and Ukraine aimed at the conceptualization and promotion of human equality on ethnic grounds as non-discrimination. The author aims at analyzing the reasons why anti-discrimination instruments are in low demand vis-a-vis concerns about ethnic xenophobia and conflicts. The author argues that the given societies have limited incentives and institutional capabilities for the creation and effective application of anti-discrimination mechanisms. The ruling elites have no reason to regard ethnic inequalities as a challenge; civil society activists and ordinary claimants might not treat non-discrimination as an efficient remedy; and there is no commonly accepted image of injustice in inter-group relations. Moreover, the marginality of anti-discrimination agenda in the post-Soviet space begs questions about the said mechanisms' universal applicability, since the latter require preconditions that are not guaranteed.
