US President Barack Obama said Russia has "paid a heavy price for its actions" in Ukraine.
Obama commended his hosts Estonia for being "such a strong voice" in both Nato and the EU "on behalf of the Ukrainian people".
"Because we have stood together Russia has paid a heavy price for its actions," he added.
Were the Russians -as Barack Obama claims - weighed down by sanctions, or where the Ukrainians looking to cut their losses?
The new president of the European Council could be "very important" for David Cameron.
