North Korea staged a huge military parade on Sunday to mark the 70th anniversary of the nation's founding as a nation, with tens of thousands of people waving brightly colored plastic bouquets as the parade began.
While Kim did not speak, the head of North Korea's parliament Kim Yong Nam stressed in an opening speech that Pyongyang has achieved military power and that the country's new focus would be on economic development.
"Just moments ago they put on that he said very strongly that we want to denuclearize North Korea during President Trump's tenure. just said it, just said it", Trump said at a campaign rally in Montana.

The mass games involve tens of thousands of people holding up placards or dancing in precise unison and are meant to be a display of national unity.
Defectors revealed earlier this year Kim ordered his rocket scientists to develop their largest missile yet ready for the 70th anniversary.
But US spy agencies reported evidence in July that North Korea is still developing long-range missiles.
Foreign dignitaries are even expected to attend - including Chinese president Xi Jinping's righthand man Li Zhanshu.
The Democratic People's Republic of Korea, as the North is officially known, was proclaimed on September 9, 1948, three years after Moscow and Washington divided the peninsula between them in the closing days of the Second World War.
Melissa Hanham, a senior research associate at the James Martin Center for Nonproliferation Studies said the military component of the parade appeared to be scaled down this year.
Trump and Kim reached a vague agreement to work towards the denuclearisation of the Korean peninsula, but there has been little movement since and Trump has accused Beijing - North Korea's sole major ally - of complicating Washington's relationship with Pyongyang.
Mr Li also said his visit aims to implement the important consensus between Mr Xi and Mr Kim, enhance high-level strategic communication, carry out friendly exchanges in various fields and have in-depth exchanges of views on further development of the traditional friendship so as to create a better future for the China-North Korea ties, Xinhua reported.

According to footage broadcast from the scene by global TV news crews, no Intercontinental Ballistic Missiles were on display - a concession nearly certainly aimed at the United States.
But too militaristic a display this time might have risked upsetting the recent diplomatic dalliance on the peninsula, after Kim's Singapore meeting with Trump in June and his third summit with the South's President Moon Jae-in due in Pyongyang later this month.
This year's celebration, however, did not feature the isolated nation's most advanced missiles. The North Korean leader, for his part, confirmed readiness to visit Russian Federation.

The North also refrained from immediately televising the event, though North Korean media were out in force to film it, deploying booms and - for possibly the first time - drones with cameras.
Trump said on Friday that Kim has sent a letter to him, which he believes will be positive.
The "new line" of putting economic development first has been Kim's top priority this year.
