VLADIVOSTOK, Russia (AP) — Russian President Vladimir Putin says North Korean leader Kim Jong Un confirmed during their first summit he is willing to give up his nuclear weapons — but only if he gets an ironclad security guarantee first. Putin stressed that Moscow and Washington both want North Korea to abandon its nuclear weapons. But he said the security guarantees should be underwritten by multiple countries, hinting at an arrangement like the six-nation talks that collapsed in 2009.
