Speaking after the meeting with South Korean President Moon Jae-in, Russian President Vladimir Putin called for talks with North Korea, saying sanctions are not a solution to the country's nuclear and missile development.
Moon had been calling for Moscow to support stronger sanctions against Pyongyang, which conducted its sixth nuclear test on Sunday in what it claimed was a detonation of a thermonuclear weapon built for intercontinental ballistic missiles capable of reaching the US mainland.
"As never before everyone should show restraint and refrain from steps leading to escalation and tensions." Moon didn't provide details of his conversations with Putin.
He said the leaders agreed that reducing regional tension and "quickly solving" the security challenges posed by North Korea's nuclear and missile program were critical. Ahead of his meeting with Putin, Moon said that the situation could get out of hand if North Korea's missile and nuclear tests aren't stopped.
Moon, a liberal who took office in May, had initially showed a preference for a diplomatic approach on North Korea, but his government has since taken a harder stance as the North continued its torrid pace in weapons tests.
