Moscow: Russia is considering a "mirror response" to sanctions imposed by the West over the Crimea crisis, Russia`s state-run RIA news agency quoted Deputy Foreign Minister Grigory Karasin as saying on Friday. "There is such a thing as `reciprocity` in English and in Russian it is a `mirror response`," Karasin said. "It should be comparable, and I will not deny that we are thinking about it."
