President Putin's remarks were carried in a Kremlin statement issued on Friday, following the Thursday night telephone call with President Obama, the Reuters news agency reported.
"The discussion revealed the differences in the approaches and assessments of the crisis and current situation," the statement said.
During the one-hour call the US leader urged his Russian counterpart to engage with diplomatic efforts to defuse a crisis that began with anti-government protests in November and this week escalated with a threat of secession in the strategically-important peninsula of Crimea after armed men seized government buildings and military installations.
