Russia sanctions tackled

US banks were well-prepared for the Western sanctions announced so far over Russia’s aggression towards Ukraine, but they are still nailing down details and worry that new measures could increase the cost and complexity of enforcing the new restrictions, lawyers and industry executives said. US President Joe Biden said he would announce further sanctions on Russia yesterday, in addition to financial measures imposed this week. The US, the EU and Britain on Tuesday announced new sanctions on Russia after Moscow's recognition of two separatist regions in Ukraine. Chief among their targets: Russian banks and their ability to operate internationally.
