Kim Jong-un Takes Swipes at U.S., S.Korea

North Korean leader Kim Jong-un on Friday took a swipe at the American and South Korean presidents after they mooted a third North Korea-U.S. summit.

Speaking at a session of the rubber-stamp Supreme People's Assembly on Friday, Kim said the U.S. must "stop its current way of calculation, and come to us with a new calculation," according to the official [North] Korean Central News Agency.

His last summit with Trump in Hanoi in February "raised strong questions about whether the steps we took under our strategic decision were right, and gave us a sense of caution about whether the U.S. is even really trying to improve the... relationship," he added.

The U.S. came with "completely unrealizable plans" and was "not really ready to sit with us face-to-face and solve the problem," Kim said, adding that he does not "desire to see another Hanoi summit."

"By that sort of thinking, the U.S. will not be able to move us one iota even if they sat with us a hundred thousand times, and will not be able to get what it wants at all."

He also said South Korean President Moon Jae-in "should not act as an officious 'mediator' and 'booster' that adopts a vacillating stand depending on the trend," after Moon urged Trump on Thursday to hold another summit with Kim soon. But he added, "I will have patience and wait for the U.S.' resolute decision by the end of this year."

In the meantime, he warned the North faces more hardships and international sanctions must be "swept away through a wave of self-reliance and self-sufficiency."

Meanwhile, a mass rally was held in Kim Il-sung Square in Pyongyang on Sunday and state media said Kim was given the new title "supreme representative of the people."

Earlier in the Supreme People's Assembly, Kim's right-hand man Choe Ryong-hae referred to him as "supreme representative" for the first time.

The North also revised its constitution at the assembly but did not reveal the details, while promoting 36 generals.
