President Obama has said it is important to take further steps to send messages to Russia that its destabilising actions in eastern Ukraine must stop.
Speaking at a press conference in Malaysia, Mr Obama added that it would be best to be unified with the Europeans in terms of issuing sectoral sanctions.
Mr Obama said that before making any decision on sectoral sanctions on Russia, he must know what US and European partners are willing to do in the situation.
European Union foreign ministers added 13 people to their visa ban and asset freeze list over Ukraine's crisis.
Well that’s the voting over, and no surprises so far. A ‘Yes’ vote claimed to be 89% in Donetsk, and suddenly Ukraine is no more.
Nearly 90 percent of voters in eastern Ukrainian region voted for self-rule, the head of the separatist election commission said.
