Another summit with the United States is "not needed" and "not beneficial" for North Korea as long as there is no change in Washington's negotiating position, the sister of leader Kim Jong-un said Friday.

Kim Yo-jong made the remark in a statement carried by the official Korean Central News Agency after US President Donald Trump said earlier this week that he would hold another summit with the North's leader "if I thought it was going to be helpful."

"I doubt that things like the DPRK-US summit talks would happen this year," Kim Yo-jong said, though she added that "a surprise thing may still happen, depending upon the judgement and decision between the two top leaders."

DPRK is the acronym of North Korea's official name, Democratic People's Republic of Korea.

"Serious contradiction and unsolvable discord exist between the DPRK and the US. Under such circumstances, I am of the view that the DPRK-US summit talks are not needed this year and beyond, and for our part, it is not beneficial to us unless the US shows decisive change in its stand," she said.

That, however, does not mean that the North is not going to denuclearize, she said.

"We would like to make it clear that it does not necessarily mean the denuclearization is not possible. But what we mean is that it is not possible at this point of time," she said, pointing out that denuclearization can be realized only when there are "major changes" from the US.

But such changes do not mean the lifting of sanctions, she said.

"We completely ruled out the issue of lifting sanctions from the agenda of negotiations with the US," Kim said. "I believe that the previous theme of the DPRK-US negotiations, that is, 'denuclearization measures versus lifting of sanctions' should be changed into a formula of 'withdrawal of hostility versus resumption of DPRK-US negotiations.'"

"We are fully capable of living under any sanctions," she said.

Kim said the North won't go back to its previous proposal to give up its Yongbyon nuclear complex in exchange for sanctions relief from the US. The North made the proposal during last year's summit in Hanoi, but the meeting broke down without a deal as the US demanded the North give up more nuclear facilities.

Nuclear talks between the US and the North have stalled since the no-deal summit.

Kim warned that it "totally depends on how the US behaves itself whether or not it will bump into such a troublesome problem."

"The US may still worry about receiving a Christmas gift on the eve of the presidential elections, which it hasn't received so far," she added, referring to last year's threat to undertake provocative acts as a Christmas gift to the US.

She also said that the personal feelings that leader Kim has toward Trump are "undoubtedly good and solid," but the North "should not adjust its tactics on the US and our nuclear program" depending upon the relations with the US president.

Leader Kim also asked her to extend greetings wishing Trump success in his work, she said.

Talk of another Trump-Kim summit gained traction after South Korean President Moon Jae-in told European leaders last month that he would work to make one happen before the US presidential election in November.

Former US National Security Adviser John Bolton also said Trump could meet with Kim if he believes a summit would help his reelection chances. Such a meeting could happen as an "October surprise" just before the election, he said.

On Tuesday, Trump said he's open to a meeting with Kim.

"I understand they want to meet and we would certainly do that," Trump said in an interview with Gray Television's Greta Van Susteren, according to Voice of America and other news reports. "I would do it if I thought it was going to be helpful.

Asked if he thinks such a meeting would be helpful, Trump said, "Probably. I have a very good relationship with him, (so it) probably would be."

Earlier Tuesday, US Secretary of State Mike Pompeo expressed hope for continuing talks with North Korea.

"We're very hopeful that we can continue to have this conversation, whether that's at levels beneath the summit, or if it's appropriate and there is a useful activity to take place, to have senior leaders get back together as well," he said. "As for who and how and timing, I just don't want to talk about that today." (Yonhap)
