According to Yonhap news agency, Rhee Dong-yeol, who heads the South Korean Foreign Ministry's bureau of peace in the peninsula, on Wednesday left for Washington to meet US Deputy Assistant Secretary of State for North Korea Alex Wong.
The Vietnam summit between Kim and Trump towards the end of February ended abruptly without a consensus or a joint declaration between the two countries on possible denuclearization and sanction wavering. Seoul had acted as an important mediator between Washington and Pyongyang.
Yonhap said the two sides in their meeting on Thursday are expected to discuss ways to revitalize the denuclearization process after the Hanoi failure. Seoul is also likely to seek waiver of sanctions for a planned video reunions of families separated by the Korean War (1950-53), the news agency said.
South Korea and the US are also expected to discuss two projects of economic cooperation between the two Koreas that Seoul and Pyongyang want to resume, but are again subject of UN sanctions imposed on Pyongyang for nuclear weapon tests.
However, the possibility of making advances in this regard remain slim following the failure to reach an agreement at the Hanoi summit, the report said.
Although Washington and Pyongyang give different versions of what transpired at the negotiating table at Hanoi, the disagreement between the two parties hovered around the number of North Korean nuclear assets that would be dismantled and the amount of international sanctions that would be lifted as a corresponding measure.
US National Security Advisor John Bolton, who was with Trump in Hanoi, said that Washington had called for North Korea to do away with chemical and biological weapons from its arsenal, besides dismantling its nuclear programme.
