Given the task definition, example input & output, solve the new input case.
Given a paragraph, generate a claim that is supported by the given paragraph. 1) The claim must contain information from within the paragraph. 2) A sentence within the paragraph can be used as a claim. 3) The claim should not have contradictions within the paragraph. 4) The claim should be at most one sentence long.
Example: "Although the story didn't cite the cost of appendectomy emergency or urgent surgery and we wish it had, we nonetheless will give it a satisfactory score because it at least cited what the editorial writer wrote, ""A secondary benefit is the savings to the hospital generated by minimizing staff and anesthesiologist presence late in the evening and during the wee hours of the morning."" As with our harms score above, although the story didn't give absolute numbers, in this case we think it was sufficient for it to report that ""The scientists found no significant difference among the groups in the patients' condition 30 days after surgery or in the length of their operation or hospital stay."" Although the story didn't give absolute numbers, in this case we think it was sufficient for it to report that ""The scientists found no significant difference among the groups in the patients' condition 30 days after surgery or in the length of their operation or hospital stay."" Despite running less than 300 words, this story did an adequate job in explaining the quality of the evidence, including pointing out limitations. No disease-mongering here. The story meets the bare minimum requirement for this criterion in that it at least cited what an editorial stated. The focus of the story was on a study comparing emergency appendectomy with surgery done up to 12 hours later or beyond. This is the whole focus of the story and one we applaud when it begins: ""Appendectomy is the most common emergency surgery in the world, but it doesn't have to be."" There were no claims made about the novelty of this research, and we may have wished for a bit more context on this. Nonetheless, the potential for guiding future care decisions was made clear. Not applicable. Given that the story only pulled excerpts from the journal article and the accompanying editorial, and didn't include any fresh quotes from interviews, we can't be sure of the extent to which it may have been influenced by a news release."
Output: Some appendicitis cases may not require 'emergency' surgery
The paragraph mentions that "Appendectomy is the most common emergency surgery in the world, but it doesn't have to be." which is considered evidence for the output. Thus, the output is a valid claim.

New input case for you: North Korean leader Kim Jong Un vowed to work toward denuclearization at a landmark summit with U.S. President Donald Trump in Singapore in June but the two sides have made little progress. North Korea raised new doubts about a nuclear agreement on Thursday when its state media said any deal on it giving up its nuclear arsenal had to include the complete elimination of U.S. "nuclear threats". While the United States and North Korea joust over a nuclear deal, South Korea is keen to improve ties with its old rival and has been taking steps to establish links in various areas including transport and humanitarian assistance. There has been some U.S. concern that the South may be moving too quickly on building such links, given the scant progress on denuclearization. Despite that, Stephen Biegun, the U.S. special representative for North Korea, said on Wednesday as he arrived in South Korea for talks that he would be looking with aid groups at how to deliver "appropriate assistance" to the North, particularly in the winter. South Korea's special representative for Korean peace and security affairs, Lee Do-hoon, said after talks with Biegun on Thursday the United States agreed to help supply the North with the flu drug Tamiflu. "The issue of providing Tamiflu to the North Korean people was resolved," Lee told reporters. South Korea provided 500,000 doses of Tamiflu to the North in 2009 following an outbreak of H1N1 influenza. The Red Cross said in January this year that more than 81,000 North Koreans were affected by the same virus also known as swine flu. Humanitarian aid is not subject to tough sanctions on North Korea aimed at pressing it to give up its nuclear weapons and ballistic missile programs. But officials at U.N. agencies and aid groups have told Reuters that their operations have nearly ground to a halt because of the strict interpretation of U.N. curbs on banking and shipping to North Korea, as well as a travel ban for U.S. citizens. Lee said he had secured U.S. sanctions exemptions over a plan to reconnect rail and road links, as well as the joint excavation of remains of soldiers killed in the 1950-53 Korean War in the Demilitarised Zone, which is administered by the U.S.-led United Nations Command. Biegun said while the United States had no intention of easing sanctions, such cooperation could help advance the nuclear diplomacy. "Of course, all of this is intended to advance what we're trying to do with North Korea," Biegun told reporters. "Now that work begins with denuclearization but also includes the strong commitments by both of our countries to transform relations and build a permanent peace regime on the Korean peninsula," he said. Trump has said a second summit with Kim was likely in January or February, though he wrote on Twitter last week that he was "in no hurry". Biegun said the United States and North Korea had yet to agree on a date or venue for a second summit, but would work for an "agreeable outcome". "We're eager to move to the next stage of discussions with our North Korean partners," he said.
Output:
U.S. to help South Korea get flu drugs to North despite stalled nuclear talks.
