French President Francois Hollande said Europe's leaders would cancel a June summit with Russia, reports RIA Novosti.
Calling events in Ukraine and Crimea were "unacceptable", the French leader said "sanctions will be decided against a certain number of figures, regarding their personal situation or their financial assets".
"There was supposed to be a meeting between the EU and Russia but it cannot take place in these conditions," he said, referring to a planned June summit.
