Moon was given a personal account of the US-North Korea summit from US President Donald Trump himself in a 20-minute telephone conversation, held only hours after Trump met with North Korean leader Kim Jong-un in Singapore on Tuesday.

Pompeo is expected to give a more detailed account of the first-ever US-North Korea summit to Moon and his South Korean counterparts, the Cheong Wa Dae official noted.

In a joint statement issued after their historic summit, Trump and Kim said they agreed to improve their countries' relationship, a move that would inevitably require a formal end to the Korean War, in which nearly half a million American troops fought with their South Korean allies.

The Cheong Wa Dae official said there were no immediate plans for three-way talks between the two Koreas and the United States to officially end the 1950-53 war or implement other agreements between Washington and Pyongyang.

Also, no dialogue has been scheduled between Moon and the North Korean leader, the official added.

In his second and last telephone conversation with Trump in just two days, Moon offered to discuss a joint excavation program with North Korea to recover the remains of US soldiers killed or captured in the Korean War, Cheong Wa Dae said earlier. (Yonhap)
