Geneva: South Korea's nuclear envoy has called on North Korea to comply with U.N. Security Council (UNSC) resolutions on the North's nuclear and missile programs and return to the dialogue table, Seoul's foreign ministry said Tuesday.

According to Yonhap News Agency, Jeong Yeon-doo, vice minister for diplomatic strategy and intelligence, made the call at the high-level segment of the Conference on Disarmament held Monday in Geneva, Switzerland. He urged the DPRK to respond to sincere efforts and engage constructively in dialogue, emphasizing the need for full compliance with the Treaty on the Non-Proliferation of Nuclear Weapons and relevant UNSC resolutions.

DPRK is the acronym of North Korea's official name, the Democratic People's Republic of Korea. Jeong also expressed concerns about North Korea's military cooperation with Russia, stressing that such cooperation should cease immediately as it undermines international peace and security.

Seoul's envoy reiterated the goal of complete denuclearization of the Korean Peninsula, acknowledging that achieving this goal will take time. He explained that South Korea is pursuing a phased denuclearization approach, starting with stopping North Korea's nuclear and ballistic missile programs through dialogue and negotiation, moving to reduction in the medium term, and ultimately proceeding to dismantlement in the long term.

North Korea has remained unresponsive to dialogue overtures by President Lee Jae Myung. The North's leader Kim Jong-un has declared inter-Korean ties as those between "two states hostile to each other," vowing not to seek unification with the South.
