MOSCOW, February 27. /TASS/. Crimea is an integral part of Russia and its return to Ukraine is impossible, Kremlin Spokesman Dmitry Peskov told reporters on Monday.

When asked if Moscow could imagine a situation where Crimea would become part of Ukraine again, he answered in the negative. "It is an integral part of the Russian Federation," the presidential spokesman stressed.

US President Joe Biden assumed earlier that potential agreements on the Ukraine issue could include a provision on Kiev taking control of Crimea and some other territories in the future.

After the February 2014 coup in Ukraine, the Crimean authorities held a referendum on reuniting with Russia. Most voters supported the idea (96.7% in Crimea and 95.6% in the city of Sevastopol), with turnout reaching 80%. In March 2014, Russian President Vladimir Putin signed a treaty on Crimea’s reunification with Russia on March 18, 2014, which was ratified by the Federal Assembly on March 21, 2014.
