"Therefore, when the two sides asked us to host the meeting, we can not say no". It heralded the summit as part of a "changed era".
It also offered a list of Pyongyang's talking points, saying Kim and Trump will exchange "wide-ranging and profound views" on establishing a new relationship, the issue of building a "permanent and durable peace mechanism" and realizing the denuclearization of the Korean Peninsula.
Under Kim, Pyongyang has made rapid progress in its weapons technology, carrying out by far its most powerful nuclear test to date past year and launching missiles capable of reaching the USA mainland.
President Trump has said he will use the summit, scheduled to begin Tuesday, to push for North Korea's denuclearization. "We will not be surprised by any scenario", said the official.
The Trump-Kim summit is expected to cost about S$20 million ($15 million), Lee told Singaporean media on Sunday, with security costs representing about half the total.

Mr Kim said "the entire world [was] watching" while Mr Trump said he had a good feeling about the summit.
Trump will also meet staff from the U.S. embassy in Singapore on Monday afternoon, the White House said on Sunday.
Trump has said he hopes to make a legacy-defining deal for the North to give up its nuclear weapons, though he has recently sought to minimize expectations, saying more than one meeting may be necessary.
Word does get around, however, and the prospect of a meeting between Kim and Trump had already been on the public's radar. He described it as a "get to know you plus" meeting.
The KCNA added that Kim was accompanied on his trip to Singapore by officials, including Kim Yong-chol, vice chairman of the Central Committee of the Workers' Party of Korea, and Ri Su-yong, vice WPK chairman on global affairs, and No Kwang-chol, minister of the People's Armed Forces.
His sister and close aide Kim Yo Jong is also in Singapore, and is believed to have travelled separately on the ageing Soviet-made Ilyushin-62 that is Kim's personal aircraft.
She emerged as an influential figure in Pyongyang's opaque leadership in February, when she led a North Korean delegation to the Winter Olympics in South Korea.
Bolton's hardline rhetoric last month infuriated North Korea and almost derailed the summit.
The flight was only his second out of North Korea since he assumed power in 2011 after the death of his father, Kim Jong Il.
