Both governments had their respective victories, but Kim was the bigger victor. Isolated North Korea has long craved worldwide recognition and the prestige of being seen as a nuclear state. Kim also hopes to earn global prestige for his government; to gain recognition, particularly from Washington, of North Korea as a nuclear weapon state; to move US troops off the Korean Peninsula; and to generally weaken the US-South Korea alliance. In my meetings with North Korea's foreign ministry, its officials have repeatedly emphasized that only a leader-to-leader dialogue could break the nuclear impasse.
Trump is probably "talking about a statement of intent, not about signing an actual peace treaty, which would require a number of time-consuming steps and negotiations to complete", Ferial Saeed, a former State Department official, wrote recently. Mr Lee will meet Mr Kim on Jun 10 and Mr Trump on Jun 11.
Trump days later announced that the summit was back on but has remained only cautiously optimistic about how the historic meeting would pan out.
SBS News spoke to members of Australia's Korean community and others with a connection to North Korea about their hopes for the summit.
Media said Trump was likely to arrive at the Paya Lebar air base, where previous US presidents landed on visits to Singapore. I don't think they will try and kick out the president.
"It's the formative experience in their life and they're committed to the Australia-Korea relationship in a much deeper way to the more cosmopolitan South Korean who goes skiing in America", Dr Dalton told SBS News. In 1999, United States inspectors found no evidence of violations of the Agreed Framework and talks on a high-level North Korean visit to the USA began.
Hundreds of North Korean security experts have no doubt been up nights wondering how to safeguard Kim Jong Un since Trump shocked the world by accepting the North's invitation to meet.

There are a lot of people that believe that he's not for the people or doing things that's right by the people. I'm not too into politics, so I don't know all his other views, but his rhetoric I definitely don't agree with.
"I think within the first minute, I'll know", Trump said, prompting a reporter to question how he would know.
The president said: "I think within the first minute I'll know". "We're going to have to see what happens".
Australia can play an important role in achieving peace on the Korean Peninsula, he added.
In sum, it is far from clear that Pyongyang has really committed to anything like the American conception of denuclearisation.
Trump's remarks came after an uncomfortable overnight visit to the G-7 meeting where he and the other world leaders struggled to bridge their differences on trade and other matters. Kim, meanwhile, "is focused on the survival of his regime, beginning with the recognition of his country as a legitimate state, followed by an easing of economic sanctions", Yun wrote. While the USA has not lifted any of its sanctions, Trump has said he will not add any new sanctions before the summit.
He previously also made an appearance at the Winter Olympics in Gangneung in South Korea in February, bewildering North Korean cheerleaders who initially thought their leader had walked into a hockey stadium.
South Korean President Moon Jae-in, a longtime dove who has met twice with Kim in recent weeks, "is putting tremendous faith in a sudden conversion of Kim Jong Un to better behavior", according to Robert Kelly, a political science professor at Pusan National University in Busan.
