Vladimir Putin has no soul, U.S. Vice President Joe Biden concluded after meeting with the Russian leader at the Kremlin in 2011, according to an article in the New Yorker published online on Monday.

Biden told the magazine about his 2011 visit with Putin, who at the time was prime minister, and said he found himself just inches away from the Russian leader.

"I said, 'Mr. Prime Minister, I'm looking into your eyes, and I don't think you have a soul,' " Biden told the magazine. "He looked back at me, and he smiled, and he said, 'We understand one another.' "
