Moon made the remarks as he began a summit with Trump in the South Korean capital, Seoul, before their joint trip to the DMZ. Earlier during the G20 Summit Trump suggested that if North Korean leader Kim Jong Un would also be there at his invitation, they would see each other "for two minutes" and shake hands.
The summit in February between Kim and Trump ended up without any agreement, as the two leaders were unable to bridge differences between US demands for denuclearization and North Korean demands for sanctions relief. Trump previously said he was in "no rush" to reach a deal with North Korea on its nuclear weapons.
