"Obama said the Russian economy is 'in tatters' thanks to US… What a dreamer," Rogozin said in a Twitter post.
In his state of the nation address to Congress, Obama claimed that almost a year after Russia's alleged "aggression" against Ukraine, Washington succeeded at isolating Moscow, leaving its economy severely damaged.
Over the past year, the United States and its Western allies have imposed several rounds of sanctions against Russia, culminating with economic restrictions that targeted the country's energy, defense and banking sectors, as well as certain individuals.
Russia argues its economic turmoil is due to the historic fall in global oil prices, and to a much lesser extent, sanctions placed on the country. In August, Moscow retaliated with a one-year ban on food imports from countries involved in the sanctions on Russia.
