Citing Russia's stalled growth rate and a flow of foreign capital out of Moscow, U.S. and European officials hope a new round of sanctions targeting energy and defense entities, as well as major banks, will deepen Russia's economic pain even further and force President Vladimir Putin to end provocations in Ukraine. Roughly 30 percent of Russia's banking sector assets are now constrained by U.S. sanctions, Obama administration officials said, shortly after announcing new penalties.
Struggling to defuse the persistent crisis in Ukraine, both the U.S. and European Union imposed new economic sanctions on Russia Wednesday, with President Barack Obama declaring that Russian leaders must see that their actions supporting rebels "have consequences."
