Sustainable Development Goal (SDG) 16 ‘Peace, Justice and Strong Institutions’ is one of 17 SDGs identified by the UN in 2015. The SDGs that supersede the Millennium Development Goals imply continuous multilateral actions to ensure their full and timely implementation. Analysis of the available literature shows that insufficient attention is paid to the international component of SDG implementation. An insufficient examination of Russia’s participation in international initiatives to implement the SDGs, and SDG 16 in particular, is also noted. This article intends to fill in this gap by presenting the results of an analysis of Russia’s activities in the international arena, contributing to the implementation of SDG 16. Russia today is one of the key actors in international politics. Russia’s activities in the international arena, including its participation in multilateral programs of assistance to countries and regions experiencing difficulties in resolving internal conflicts, contribute to the implementation of SDG 16. However, this aspect is not covered in Russia’s Voluntary National Review for the High-Level Political Forum, nor in available research. The author examines the features of a modern approach to studying the international aspect of the SDG’s implementation. Furthermore, the author analyzes Russia’s activities on the international arena contributing to SDG 16 implementation. The article concludes with the author’s observations regarding appropriate steps to increase Russia’s contribution to SDG 16 implementation.
