United States Treasury Secretary Janet L Yellen on Thursday said Russia's economy has become increasingly isolated and the impact of sanctions against that country for war against Ukraine is being seen.

"Since the early days of the war, we have partnered with a multilateral coalition of over 30 countries to impose severe economic costs on Russia for its brutal assault. Our twin goals are to degrade Russia's military-industrial complex and reduce the revenues that it can use to fund its war. We are seeing the impacts of these actions," Yellen said.
