"It is essential for the U.S.to quit its current calculation method and approach us with new one", Kim said in a speech to the Supreme People's Assembly on Friday, KCNA said.
Kim said that the North would not stick to summits with the USA for the sake of easing sanctions but it will wait with patience until year's end for a courageous decision from the US, setting an effective deadline for a shift in the USA demands in denuclearization talks.
In Hanoi, Pyongyang offered to close its main nuclear facility in return for sanctions relief, but Washington sought a "big deal" comprising - in details which have emerged post-summit - the demand that North Korea surrender all its nuclear arms and weapons of mass destruction.
Kim said he would wait until the end of the year "for the USA to make a courageous decision" to change its approach and smooth the path to another meeting, state media reported, after his most recent summit with Trump in Vietnam broke down without agreement.
Trump responded to the remarks by saying he agreed with Kim about their relationship, and also expressed a desire for another summit.
The United States had continued to provoke North Korea by testing an anti-ballistic missile system and conducting military drills with South Korea despite Trump's announcement that large-scale exercises would end, he said.
"North Korea has tremendous potential for... extraordinary growth, economic success and riches under the leadership of Chairman Kim", Trump added.
Kim also complained that the US had resumed military exercises with South Korea this year, despite what he said was a direct commitment by Trump to suspend them.

Kim said the United States has been refusing to withdraw what the North perceives as "hostile policies" while sticking to "mistaken judgment that we would succumb to maximum pressure". Kim wants major sanctions relief and resources for his country before he'll take even minor steps toward eliminating his nuclear stockpile.
Still, North Korea is committed to better North-South relations and peaceful unification, Kim said. "But it will clearly be hard for a good opportunity like last time to come up".
Jeong Young-tae, an analyst at the Institute of North Korean Studies in Seoul, says the new title is part of Pyongyang's efforts to "secularise" Kim and his power.
In the months since Hanoi, there have been no known follow-up negotiations between Washington and Pyongyang.
There would be no improvement in north-south ties unless South Korea ended military exercises with the United States, he said, "and unless a fundamental liquidation is put to the anachronistic arrogance and hostile policy of the US which creates a deliberate hurdle in the improvement of ties while coming forward with unilateral gangster-like demands".
North Korea has spent decades building up its nuclear program, which it views as a deterrent against the U.S.
