"Nuland was denied a Russian visa, as it is included in the black lists introduced in response to similar measures of the United States," RIA Novosti reports the Russian Foreign Ministry.
As reported by Kommersant, Nuland applied for a Russian visa to take part in a closed international conference in Moscow from May 20 to 21.
The event was organized by the Russian International Affairs Council (INF), the German Society for Foreign Policy (DGAP) and the Johns Hopkins University School for Advanced International Studies (SAIS).
Assistant Secretary of State for European and Eurasian Affairs Victoria Nuland left her post in January 2017.
