Already in the coming months, the Russian economy will be in a catastrophic situation, Oleksiy Arestovych, adviser to the head of the President's Office, has said.

"According to Western experts and leading world economists, in a month or two the Russian economy will experience a catastrophe. It will be just a catastrophe. Now the Russian economy is going by inertia for a certain time, but then there will be a catastrophe," Arestovych said during a telethon on Saturday.
