Ban said that South Korean President Park Geun-hye made successful diplomatic efforts to respond to the North Korea’s actions, Chung claimed.
He also noted that China would play a key role in resolving the North Korean nuclear issue, according to Chung.
On September 9, Pyongyang carried out a nuclear test at its northeastern nuclear test site. The nuclear experiment is believed to be the fifth and the largest since North Korea started pursuing nuclear and ballistic missile programs, drawing condemnation from the international community.
South Korea has also reportedly developed a preemptive attack plan against North Korea aiming to destroy the northern capital, Pyongyang, in case of a nuclear attack emanating from the north.
