"We hold such expert consultations with the United States regularly. We maintain permanent dialogue regarding, among other things, the normalisation of work of Russian missions in the United States," the source said.
Russian media previously reported, citing US Ambassador to Moscow Jon Huntsman, that Russia and the United States held consultations in Vienna on 11 September regarding a possible increase in the number of diplomatic personnel in both countries.
In September 2017, Russia closed down its Consulate General in San Francisco and two diplomatic properties in New York City and Washington, DC, following an order of the United States.
Washington’s demand came after Moscow announced in July 2017 that the diplomatic presence of the United States in Russia would be scaled down by 755 people to 455, the same number of diplomatic personnel Russia has in the United States since late 2016 when 35 Russian diplomats were expelled from the United States.
