Please answer the following question: SEOUL, SOUTH KOREA — North Korea and its neighbors in the region reacted with caution to U.S. President Donald Trump’s decision Thursday to cancel the U.S.- North Korea nuclear summit. North Korean Vice Foreign Minister Kim Kye Gwan said in a statement released by the North’s central news agency (KCNA) that his country remains open to resolving problems with the United States “whenever and however,” and offered praise for President Trump’s diplomatic engagement efforts. “We had held in high regards President Trump’s efforts, unprecedented by any other president, to create a historic North Korea-U.S. summit,” said the vice foreign minister in a statement released Friday by KCNA. The conciliatory tone that came from Vice Foreign Minister Kim stands in sharp contrast to earlier criticisms, insults and threats made by another North Korean official that prompted Trump to cancel the June summit in Singapore with North Korean leader Kim Jong Un. On Thursday North Korean Vice Foreign Minister Choe Son Hui called U.S. Vice President Mike Pence a “political dummy” and threatened a “nuclear-to-nuclear showdown” with the U.S. over comments made by Pence calling for North Korea to follow the Libya denuclearization model. The Libya model refers to the rapid and complete dismantlement of that country’s nuclear program in 2003 and 2004, before the easing of any sanctions. But North Korea is acutely aware that Libyan leader Muammar Gaddafi was overthrown and killed by his own people a few years later, with support from a multinational military coalition that included the United States. Pyongyang has called for a more incremental process that links concessions to partial nuclear reductions and postpones complete denuclearization until its undefined security demands are met. Trump blamed the “tremendous anger and open hostility” from Pyongyang for forcing the cancelation of the summit, but many analysts say the issue was more about substance over tone and the unbridgeable gap between the two denuclearization positions. But... Question: What is the U.S. trying to obtain from North Korea?

Answer:
