South Korea's National Security Council reaffirmed the importance of stabilizing the situation on the Korean Peninsula and said that there shouldn't be any actions to heighten tensions in the region.
The top office held an NSC meeting on Friday and discussed North Korea issues following Pyeongyang's latest ballistic missile launch.
The Blue House said the participants agreed to cooperate with the relevant nations to resume dialogue with North Korea, based on recent discussions between Seoul and Washington regarding their joint projects on North Korea.
Meanwhile, the Chief of the International Atomic Energy Agency, Rafael Grossi expressed concerns about Pyeongyang's nuclear activities, saying that it has expanded over the years and continues to move ahead at full steam.
In a webinar hosted by the U.S.-based Stimson Center think tank on Thursday local time, he said compared the situation to 2009, the North's nuclear program increased its activity and grew geographically.
He also noted that Pyeongyang could be working on "every possible and imaginable area" at its disposal.
The U.S. envoy for North Korea, Sung Kim will visit Seoul on Saturday to talk with his South Korean counterpart Noh Kyu-duk about denuclearization on the Korean Peninsula and a formal end to the Korean War.
Kim's trip to Seoul was initially scheduled to begin on Friday, but was delayed according to a source who did not elaborate on the reason.
The two envoys had met earlier this week in Washington, where they held a trilateral meeting with their Japanese counterpart, to discuss ways to restart the peace process as soon as possible.
