Moscow regrets North Korea's unilateral withdrawal from an agreement with South Korea on the nuclear-free status of the Korean peninsula.
When addressing a news conference in Moscow, Russian Defence Minister Sergei Ivanov described this step of North Korea as deplorable.
He then urged for more intensive politico-diplomatic steps towards the Korean settlement.
The minister said it was not that important in which format the settlement effort would proceed - involving the United States and North Korea only or all the countries neighbouring the region, i.e. South Korea, Japan, China and Russia in the first instance.
"Russia has always advocated a nuclear-free status for the Korean peninsula, North Korea's rejoining all the non-proliferation understandings, including the Treaty on the Non-proliferation of Nuclear Weapons, and the unconditional respect for the North's sovereignty and legitimate security interests," said Mr Ivanov.
