"That is, you want justice according to Nazi patterns? Then make a decision there, in the Czech Republic, to return the Sudetenland to the Germans and restore the Sudetenland," Medvedev wrote.
President Vladimir Putin has repeatedly stressed that the issue of Crimea is closed for Russia, and the referendum on the peninsula was held in strict accordance with international law.
Crimea became a Russian region after a referendum held there in March 2014, when a majority of residents voted in favor of reunification with Russia.
