Donald Trump wants North Korean leader Kim Jong Un to know that he likes him and will fulfill his wishes, South Korea's President Moon Jae-in said on Sunday, a day after meeting the USA president at an economic summit in Argentina.
Trump also said that "at some point" he would invite Kim to visit the USA, though he gave no indication of when.
"We're getting along very well".
Moon has facilitated a series of high-level talks between the USA and North Korea, including a summit between Trump and Kim in June, and has met Kim three times this year.
Moon's spokesperson Kim Eui-Kyeom appreciated Trump's comment on second meet with Kim and said, "We hope a concrete agenda and logistics will be determined soon".
In June, Trump and Kim opened up a face-to-face dialogue after months of trading military threats and pointed barbs.
Trump also met with Japanese Prime Minister Shinzo Abe on Friday, when they reviewed the recent developments in the DPRK and discussed how best to work with the global community, including South Korea, to maintain pressure until the DPRK implements its commitment to denuclearise.

In November the vice-president, Mike Pence, said Trump would push for a concrete plan outlining Pyongyang's moves to end its arms programmes.
They agreed on the need for "maintaining vigorous enforcement of existing sanctions to ensure the DPRK understands that denuclearization is the only path", Sanders said, using the North´s official name, the Democratic People´s Republic of Korea.
North Korea had been angered by Washington's refusal to ease sanctions and has warned it could resume development of its nuclear program if the United States did not drop its campaign.
Negotiations between the US and North Korea on ending its nuclear program have appeared to stall in the months since Trump and Kim held a historic summit in Singapore in June.
To improve long-strained relation between the South and North Korea, they both have started their mission by removing landmines and also destroying military bunkers at their border.
Despite the warming ties, it remains unclear whether Kim will make his first-ever visit to the South this year, as Seoul is hoping.
