Donald Trump has offered to meet the North Korean leader Kim Jong Un at the demilitarized zone (DMZ) on the Korean border.
The US President made the surprise offer at the end of the G20 summit in Japan, and ahead of a two-day visit to South Korea.
He suggested he wanted to meet the North Korean leader "just to shake his hand and say hello".
President Trump told reporters in Japan: "We spoke with people... Kim Jong Un was very receptive.
"We get along. There's been no nuclear tests... there's been no long-range ballistic tests... they gave us back our hostages, which was great.
"I let them know we'll be there. We'll see. I can't tell you exactly, but they did respond very favourably."
Pyongyang has described the offer as a "very interesting suggestion".
The country's foreign minister said if the visit becomes a reality it would be a "meaningful occasion" in furthering the relationship between the two leaders.
The first year of the Trump administration saw tensions between the US and North Korea intensify - with both leaders trading insults amid a series of North Korean missile tests.
However, the situation deescalated amid fresh diplomatic efforts - culminating in an historic summit between the two leaders in Singapore in June 2018.
A second summit took place in Vietnam earlier this year.
That meeting ended early and without agreement, as talks focused on denuclearisation of the Korean peninsula collapsed.
Communications between the two countries have continued, however, with President Trump saying earlier this month he had received a "beautiful letter" from Kim Jong Un.
A meeting between the two men at the DMZ - which was created in 1953 following the end of fighting in the Korean War - would be a major symbolic occasion.
Last year, Mr Kim met South Korean President Moon Jae In at the Panmunjeom 'peace village' for the first summit between the two countries in more than a decade.

Mr Moon also briefly yet symbolically stepped into northern territory after an apparently unscripted invite from Mr Kim.
