The Russian president said his country does not want to get in other regions of Ukraine
President Vladimir Putin signed the annexation of Crimea to Russia and said it is a way of correcting injustices and a necessary response to what he called a Western invasion of the vital interests of Russia.
"In the hearts and minds of people, Crimea has always been an integral part of Russia," Putin said in a speech of 40 minutes in the Kremlin.
The Russian president has rejected Western criticism of the Sunday Crimean referendum, in which residents of the strategic Black Sea peninsula overwhelmingly supported secede from Ukraine and join Russia.
The treaty must be approved by the Constitutional Court of Russia and ratified by both houses of parliament, but is discounted to be a formality and will approve within days.
