"We were talking about how sanctions could be rolled back if and when the Minsk agreements were fully implemented. And now after the past week of flagrant violations of Minsk [agreements], on both sides of the Atlantic we are forced to talk about the need to increase costs on Russia," Victoria Nuland said at the Brookings Institution.
Existing US and EU sanctions "are the direct result of the policy decisions Moscow has taken to mess in the affairs on another country," Nuland said, arguing they were already imposing costs on Russia and its citizens.
In April 2014, a military confrontation broke out in Ukraine, with Kiev launching a military operation in eastern Ukraine in an attempt to suppress independence supporters in Donetsk and Luhansk.
Western countries have accused Russian authorities of escalating the crisis in Ukraine, and implemented several rounds of sanctions against Moscow, targeting Russia's finance, defense and energy sectors, as well as certain individuals.
Russia has denied allegations concerning its involvement in Ukraine's internal affairs and repeatedly called for a political solution to the existing tensions in eastern Ukraine.
