South Korea's chief nuclear envoy called for North Korea Thursday to immediately halt all its nuclear activities, accusing Pyongyang of violating U.N. resolutions by continuing to develop its nuclear and missile arsenals.
  

Hwang Joon-kook, South Korea's chief negotiator to the long-stalled six-party talks on North Korea's nuclear ambitions, also said that Seoul and Beijing agreed that Pyongyang should stop such "wrong behavior," including a fresh nuclear test.
  

"Even though North Korea is not conducting a nuclear test at this point, I can't say that the situation is good," Hwang told reporters after wrapping up his two-day visit to Beijing, where he held talks with his Chinese counterpart, Wu Dawei.
  

"At this very moment, North Korea is operating its nuclear facilities and continuing to advance its nuclear and missile capabilities, thereby violating U.N. Security Council resolutions day after day." Hwang said. "North Korea must immediately halt its nuclear activities."
  

Recent satellite images have showed that North Korea appears to be attempting to restart its main nuclear reactor that had provided bomb fuel after a five-month shutdown.
  

Despite his unusually blunt remarks on North Korea's nuclear ambition, Hwang said he and Wu have narrowed differences on conditions about restarting negotiations over the North's nuclear ambition.
  

"I had productive and in-depth consultations with Special Representative Wu Dawei and both sides were approached by some opinions on conditions to resume the six-party talks," Hwang told reporters, without elaborating on the details.
  

Last week, the top U.S. diplomat handling North Korea, Ambassador Sung Kim, told reporters in Beijing that Pyongyang was not ready for "serious and substantive" nuclear talks with Washington, indicating that a bilateral meeting in Beijing with North Korean officials had been discussed.
  

North Korea shifted the blame for a deadlock on the nuclear diplomacy to the U.S. on Sunday, revealing that Pyongyang invited Kim to visit the North for direct talks, but Washington rejected the offer.
  

The six-party talks on North Korea's nuclear programs -- involving the two Koreas, the U.S., China, Japan and Russia -- have been dormant since late 2008, when Pyongyang walked away from the bargaining table.
  

Pyongyang has called for the resumption of the six-party talks without preconditions following its third nuclear test in February 2013. But Seoul and Washington have insisted that the North should first show its sincere commitment towards forgoing its nuclear weapons program but added Pyongyang has yet to show its seriousness about denuclearization.
