'This was a productive meeting' -Putin

Putin described Biden as a constructive and experienced partner and said the two leaders spoke "the same language" at a summit in Geneva, describing the talks as pragmatic and fruitful. He said it was hard to say whether relations with the United States would improve, however.

Putin also said Moscow and Washington will begin discussions on possible changes to the recently extended New START arms control treaty, adding that the two countries are responsible for nuclear strategic stability.
