In a chief aides meeting held at the presidential office, Moon said he hopes Trump and Kim "generously" consider each other's demands and meet the people's wish for a new era for the Korean Peninsula.
Q. Where will the meeting be held?
Commenting for the first time on the summit, North Korea's state-run KCNA news agency earlier said the two sides would exchange "wide-ranging and profound views" to re-set relations.
Q When is the meeting?
After shaking hands with Singapore's foreign minister, Mr Kim sped through the streets in a limousine, two large North Korean flags fluttering on the auto, surrounded by other black vehicles with tinted windows and bound for the luxurious and closely guarded St Regis Hotel.

Trump was scheduled to attend a meet-and-greet at his hotel with U.S. Embassy personnel.
Q. What is on the agenda?
North Korea must take "concrete" steps towards denuclearisation before benefiting from any relaxation of worldwide sanctions, Downing Street has said. He declined, however, to reveal any details of the preliminary discussions being held Monday between US and North Korean officials.

Q. First activity after arrival?
The sudden change in schedule added to a dizzying few days for foreign policy for Trump, who shocked US allies over the weekend when he used a meeting of the Group of 7 industrialized economies in Canada to alienate America's closest friends in the West. Lashing out over trade practices, he lobbed insults at the G-7 host, Canadian Prime Minister Justin Trudeau.
Q. What's in it for Singapore?
It's the summit eve in Singapore.
"It's our contribution to an worldwide endeavor which is in our profound interest", Lee told reporters Sunday at the global media center the city-state set up to accommodate the more than 2,500 journalists covering the event.
Q. What to expect from the summit?
Delegates were outlining specific goals for what Trump and Kim should try to accomplish and multiple scenarios for how key issues can be resolved, an official briefed on the discussions said.
The fighting ended on July 27 1953 but the war technically continues today because instead of a difficult-to-negotiate peace treaty, military officers for the US-led United Nations, North Korea and China signed an armistice that halted the fighting. North Korea is seeking a security guarantee - possibly including a peace treaty formally ending the Korean War - and the removal of the US's nuclear umbrella protecting allies South Korea and Japan. This summit marks the thawing of ties and the hope that North Korea may let go of at least some of its armaments.
