Seoul, Dec 1 South Korea welcomed a new resolution of UN Security Council on North Korea, adopted in response to Pyongyang's fifth nuclear test in September, media reports said.
Seoul's foreign ministry said in a statement that the fresh resolution was aimed at taking punitive action on North Korea, issuing strong warnings against newly possible provocations and re-declaring a strong will to never accept North Korea's nuclear and missile programs.
The statement was announced right after the UN Security Council unanimously adopted the resolution to tighten sanctions on North Korea, Xinhua news agency reported.
The fifth test was carried out just eight months after Pyongyang's fourth nuclear detonation in January, which was followed by the launch of a long-range rocket in February.
South Korean ministry described the new resolution adoption as a "milestone" action, saying it was the toughest-ever and the most comprehensive non-military sanctions in UN history.
South Korea vows to closely cooperate with UN members to thoroughly and completely implement the resolutions.
