WASHINGTON (AP) - Russian President Dmitry Medvedev is praising President Barack Obama for his nuclear security summit and improved relations with Russia.
But the Russian leader also is seeking to temper U.S. expectations for biting sanctions against Iran.
Medvedev praised a new atmosphere between Washington and Moscow and said that cooperation is starting to yield results.
In a speech Tuesday, Medvedev cited the completion of a new U.S.-Russian nuclear arms reduction treaty. He called the nuclear security summit hosted by Obama a "complete success."
Medvedev said that world powers will have to consider sanctions against Iran over its nuclear intentions. However, the Russian leader said he opposes crippling sanctions.
