MOSCOW, January 17. /TASS/. Russian Foreign Intelligence chief Sergey Naryshkin said on Tuesday that the ‘return’ of Crimea to Ukraine is impossible.

"This is impossible," Naryshkin told TASS commenting on Kiev's recently announced intentions to launch work on ‘returning back Crimea.’

The Republic of Crimea and Sevastopol, a city with a special status on the Crimean Peninsula, where most residents are Russian, refused to recognize the legitimacy of authorities that seized power amid riots during the illegitimate coup of February 2014 in Ukraine.

Crimea and Sevastopol adopted declarations of independence on March 11, 2014. They held a referendum on March 16, 2014, in which 96.7% of Crimeans and 95.6% of Sevastopol voters chose to secede from Ukraine and join the Russian Federation. Russian President Vladimir Putin signed the reunification treaties on March 18, 2014. The documents were ratified by Russia’s Federal Assembly, or bicameral parliament, on March 21.

Despite the overwhelming results of the referendum, Ukraine still refuses to recognize Crimea as part of Russia.
