WASHINGTON (AP) — President Barack Obama says he's had mixed success in persuading Russian President Vladimir Putin to think "forward as opposed to backward" on a variety of issues and is reassessing the U.S.-Russia relationship.

Obama told reporters at a news conference Friday that Putin's return to the Kremlin last year has brought about more rhetoric on the Russian side that is anti-American and plays into old stereotypes about the Cold War contest between the nations.

Obama told reporters that he decided not to attend a summit with Putin planned next month for Moscow because "Russia has not moved" on a range of issues where the U.S. would like to see progress.

He says his unhappiness with Russia granting temporary asylum to NSA leaker Edward Snowden wasn't the only reason for his decision.
