US, S Korean Officials Discuss ‘Verified Denuclearization’ of DPRK – State Dept

US Deputy Secretary of State John Sullivan and South Korean National Assembly Speaker Moon Hee-Sang during a meeting vowed that their respective countries will closely coordinate on efforts to denuclearize the Korean peninsula, State Department spokesman Robert Palladino said in a press release.

“The Deputy Secretary and National Assembly Speaker reaffirmed the ironclad alliance between the United States and the Republic of Korea and pledged to maintain close coordination to ensure the final, fully verified denuclearization of the Democratic People’s Republic of Korea”, Palladino said Monday.

US President Donald Trump announced in his State of the Union address last week that he would meet again with North Korean leader Kin Jong-un in Vietnam on 27-28 February. US Special Representative for North Korea Stephen Biegun and his North Korean counterpart Kim Hyok Chol held talks in Pyongyang on 6-8 February to prepare the ground for the second Trump-Kim summit.  
During the summit, the sides reached an agreement stipulating that North Korea would make efforts towards complete denuclearization in exchange for the United States and South Korea freezing their military exercise and potentially lifting US sanctions.
