MOSCOW, March 20. /ITAR-TASS/. The decision of Crimea to reunite with Russia, “reflecting the will of the absolute majority of its residents, is not subject to revision”, Russian Foreign Minister Sergey Lavrov told his US counterpart John Kerry on Thursday.

“The heads of the foreign policy departments continued discussing the situation in Ukraine and possibilities of international assistance in overcoming the political crisis in that country, including through organization of an international mission acceptable to all Ukrainians that would monitor the observance of human rights and ethnic minorities,” the Russian Foreign Ministry reported.

The Republic of Crimea, where most residents are Russians, held a referendum on March 16, in which 97% of its population voted for secession from Ukraine and joining Russia, and subsequently signed a treaty with Moscow on Crimea's accession to the Russian Federation as a constituent member on Tuesday.
