The Russian Foreign Ministry said in a statement on its website Monday that it expressed deep regret over the Ukrainian leadership's decision to terminate the Russian-Ukrainian Treaty on Friendship, Cooperation and Partnership.
"The destructive steps taken by the current leadership of Ukraine cause deep regret," the Russian ministry said.
It said the Russia-Ukraine crisis will be overcome, adding that relations will obviously have to be restored with more responsible Ukrainian politicians.
The ministry stated that by denouncing the Friendship Treaty with Russia, Ukraine shows it is ready to easily destroy all that has been built in bilateral relations in the past decades.
