Commenting on the sanctions imposed by the US and the EU in the aviation industry, the diplomat slammed the restrictions as "an unprecedented attempt to influence Moscow's foreign policy decisions."
Russia is currently working on its economic response measures, the diplomat said, noting that at the stage of development, this work is mostly non-public. Russia's reaction will be prompt, thoughtful and sensitive for those targeted, he added.
