Mr. Kim made the comments during a speech Friday at a session of the North Korea's rubber-stamp parliament, which made a slew of personnel changes that bolstered his diplomatic lineup amid stalemated negotiations with the United States.
"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.
The Democratic People's Republic of Korea (DPRK) leader Kim Jong Un has expressed a willingness to hold a third summit with U.S. President Donald Trump, the Korean Central News Agency (KCNA) reported Saturday. "We will wait with patience until the end of the year for the United States to come up with a courageous decision".
Trump said on Thursday he was open to meeting Kim again, but in his speech on Friday, the North Korean leader said the outcome in Hanoi had forced him to question the strategy he embraced a year ago of global engagement and economic development.
In Hanoi, the United States came with "completely unrealizable plans" and was "not really ready to sit with us face-to-face and solve the problem", Kim said.
The day before Kim accused Seoul of acting as an "overstepping mediator" and said the South should "speak up" for Pyongyang's interests.
Washington has blamed the February deadlock on the North's demands for sanctions relief in return for limited nuclear disarmament, but Pyongyang said it had wanted only some of the measures eased.
He said the USA "mistakenly believe that if they pressure us to the maximum, they can subdue us" and called on them to cease "hostile" negotiating tactics.
In Hanoi, the United States came with "completely unrealisable plans" and was "not really ready to sit with us face-to-face and solve the problem", Kim said.
"But it will be hard to get a good opportunity like the last time again", he said. Mr. Kim held three summits past year with Mr. Moon, who lobbied hard to revive the nuclear talks between the United States and North Korea. South Korean analysts believe Choe is being positioned to supervise North Korea's top diplomats since one of his titles is vice chairman of the State Affairs Commission, a position his predecessor did not hold.
"What is needed is for the USA to stop its current way of calculation, and come to us with a new calculation", Kim said in a speech on Friday, Reuters reported, citing KCNA, North Korea's state media outlet.
