"We will wait for a bold decision from the United States with patience until the end of this year, but I think it will definitely be hard to get such a good opportunity as the previous summit", Kim was quoted as saying by KCNA.
North Korean leader Kim Jong Un said the breakdown in talks with the United States has raised the risks of reviving tensions, but he is only interested in meeting President Donald Trump again if the United States comes with the right attitude, state media KCNA said on Saturday.
Kim, who has recently pledged to build a "powerful socialist economy", asked the United States to ease economic sanctions, arguing it has already started to implement concrete measures toward denuclearizing the Korean Peninsula.
The failed face-to-face talks with President Donald Trump raise doubt whether the United States is really committed to improving relations with North Korea, its leader Kim Jong-un said, while promising to beef up the nation's defense. "But US-style dialogue of unilaterally pushing its demands doesn't fit us, and we have no interest in it", Mr Kim said during a speech to the North Korean Parliament. He is one of the best-known personalities involved in the nuclear talks, having met with US Secretary of State Michael Pompeo in Pyongyang and travelling to Washington earlier this year to visit Trump.
"Kim Yong Chol, the North's top nuclear negotiator, also has been sanctioned by Washington since 2010", Ahn Chan-il, the president of the World Institute for North Korea Studies in Seoul, told AFP.
"We are willing to give another try if the USA offers to have a third summit with the right attitude and mutually acceptable terms", he said, according to a report by North Korean state media outlet KCNA.
Long-serving officials such as 91-year-old Kim Jong-nam, the titular head of state, and Premier Pak Pong-ju, 80, were either retired or promoted to symbolic posts and replaced by younger officials.
"There are various smaller deals that could happen", Trump said "You could work out step-by-step pieces, but at this moment we're talking about the big deal".
While President Trump continues to give at least superficial lip-service to wanting new diplomatic process with North Korea, including possible "small deals" in the future, it appears he is also heavily committed to the status quo of sanctions and hostility.
Following the collapse of the Trump-Kim summit, the North had been urging the South to break away from Washington and proceed with inter-Korean economic projects that are now held back by US -led sanctions against the North.
In an expected move, KCNA also reported that Kim Jong Un has been re-elected as chairman of the State Affairs Commission.
Choe was one of the three officials sanctioned by the U.S.in December over allegations of rights abuses.
In his speech, Kim repeated earlier claims that North Korea's crippled economy would persevere through heavy worldwide sanctions imposed over its nuclear weapons program and that he wouldn't "obsess over summitry with the United States out of thirst for sanctions relief". In the months leading up to the talks, Pyongyang froze its nuclear and ballistic missile tests and demolished the only known nuclear test site.
