At the forefront of Abe's wishes for the summit is the release of Japanese citizens abducted by North Korea, including one 13-year old girl who was taken away from her family 45 years ago.
Iran's leaders are "much different" in recent months, Trump said, and they are no longer looking to the Mediterranean or causing trouble in Syria and Yemen.
"Certainly if it goes well". "I hope the first priority of the real meeting is to have Kim stop shooting off missiles and destabilizing the region".
"I don't think it's nice going in under those circumstances". Arrangements are under way to hold both Japan-U.S. bilateral and Japan-U.S. The 1950-53 conflict ended with an armistice but not a formal peace treaty. "Nothing other than we look forward to seeing you and we look forward to the summit and hopefully things will work out". "But that may happen", he said.
"I hope it continues on this track".
Trump also pledged to bring up the subject of Japanese abductees with Kim, after Abe focused on the issue during their earlier conversation.
"We said we're not going to have a summit under those circumstances", Giuliani, the former mayor of NY, told a business conference in Tel Aviv, Israel.
Trump warned he is "totally prepared to walk away" if negotiations break down.
Giuliani told Business Insider on Wednesday he didn't know for certain Kim had begged Trump in this regard, but said it was his "speculation".
'It's about attitude, it's about willingness to get things done, but I think I've been preparing for this summit for a long time, as has the other side.
So now we want to know how the regime did it, and most importantly, who else helped the regime to achieve that goal.
That would come after what Trump described as a diplomatic process that could include an agreement to safeguard Kim from the threat of ouster at the hands of the United States.

The trade tariffs have potential ramifications for world growth, not just for this year or next year, but the longer term. " Canada in North America is increasingly looking to the U.S.as a competitor as opposed to a trade ally", MacKay said .
Asked how many days he's willing to stay to talk with Kim, Trump said, "One, two three, depending on what happens". "It would be wonderful if it were", he said.
"They have to denuke, " he said, adding that the United States plans to keep sanctions on North Korea in the meantime. "If they don't denuclearise that will not be acceptable". Japan is a possible target of aggression from Pyongyang and previous year, a missile test carried out by North Korea ended in Japanese waters.
Tokyo is also a strong advocate of the global sanctions regime against Pyongyang.
In a joint press conference, Trump also praised Japanese-US business relations, and indicated he would like to see more Japanese auto factories in the US.
"The sanctions are extraordinarily powerful, " Trump said.
"We don't use the term anymore because we're going into a friendly negotiation", Trump said.
U.S. Secretary of State Mike Pompeo on Thursday reemphasised Washington's stance going into the talks.
He became the highest level figure from North Korea to hold talks at the White House since a senior envoy visited former US President Bill Clinton in 2000. "I'm hopeful that Chairman Kim Jong-un is prepared to make that decision for his country".
"Stability on the (Korean) Peninsula might mean the USA is freer to pursue strategic competition with China than it is now", said Corey Wallace, an Asian security analyst at Freie University in Berlin.
Above all, Trump seems most enthused by the notion of being the first sitting USA leader to hold direct talks with a scion of the ruling Kim dynasty. -North Korea summit, including through two meetings with Kim in Pyongyang.
This image shows the location of working-level talks between North Korea and the U.S.at the Panmunjom truce village in Korea. Pyongyang's definition has included the removal of "hostile" US policy, including Washington's military presence in the region and the nuclear umbrella over Seoul and Tokyo. North Korea has not made public any list of individuals in their delegation to Singapore.
"We shall never repeat the past mistakes", Mr Abe said.
