Speaking in China, Putin called for a peaceful solution to the ongoing tensions on the Korean peninsula, Russia's Sputnik news agency reported.
"I would like to confirm that we are categorically against the expansion of the club of nuclear states, including through the Korean Peninsula," Putin told reporters. "We are against it and consider it counterproductive, damaging, dangerous," he said.
But in comments that appeared aimed at the US, he said that "intimidating (North Korea) is unacceptable."
