North Korea, South Korea, Japan, China, Russia and the US began talks in 2003 with the aim of ridding the Korean peninsula of nuclear weapons but they were suspended after Pyongyang launched a ballistic missile.
"The talks today confirmed that resuming the six-party talks is possible. Not immediately, it will take a certain time, Lavrov said following the talks in Moscow with Ri Su Yong.
"The main (condition) for these talks to resume is to achieve from all sides a calm, balanced approach and, of course, not allowing any abrupt steps that would only polarize positions," he said.
"The situation is difficult but not hopeless."
North Korea promised to abandon its nuclear program in 2005 but backed away from the agreement by testing nuclear devices in 2006 and 2009, Reuters reported
