Russian President Vladimir Putin on Wednesday called US sanctions against Moscow "counterproductive and senseless" a day after Washington warned that more "economic pain" is coming.

"Sanctions are actions that are counterproductive and senseless, especially against a country like Russia," Putin said during a press-conference with his Finnish counterpart Sauli Niinisto.
