In a video message dedicated to the tenth anniversary of the reunification of the regions with Russia, Lavrov emphasized that the peninsula is an integral part of the state.

“The question of the ownership of Crimea and Sevastopol is closed.

The peninsula is an integral part of the Russian Federation,” the minister said.

Russian leader Vladimir Putin has repeatedly emphasized 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 took place there in March 2014: the majority of residents were in favor of reunification with Russia.
