U.S. foreign policy analysts were generally critical of the meeting . Analyst and columnist Max Boot wrote that the DMZ meeting was " symbolism utterly devoid of substance " and that " Kim has realized that Trump is far more pliable — and gullible — than any of his aides " and is " all too happy to enhance Kim 's legitimacy in return for , essentially , nothing . " Jean H. Lee , the director of the Center for Korean History & Public Policy , wrote that , " There 's a reason why past presidents chose not to go to North Korea while in office : Such visits grant enormous legitimacy to the Kims . " Samantha Vinograd , a member of the National Security Council during the Obama administration , said that by meeting Kim at the DMZ without preconditions attached , Trump was signaling that North Korea was " a normalized , nuclear power . " Commentator S. Nathan Park , however , viewed the third Trump – Kim meeting as a positive trust-building event that could be viewed as " necessary to get the working level talks back on track . " Park wrote that although " one must be clear-eyed to the reality that a tangible result has not yet materialized in Trump 's North Korea diplomacy , " patience could lead to more concrete impacts . China ’s foreign minister Wang Yi called the Kim – Trump DMZ meeting a " rare opportunity for peace " and said that Chinese president Xi Jinping had urged the U.S. to " show flexibility " by easing its sanctions against North Korea in gradual " action-for-action " phases , rather than offering sanctions relief only upon complete nuclear disarmament . Cheong Seong-chang of the Sejong Institute , a South Korean think tank , said that in meetings between Kim and Xi in North Korea , " Xi pledged economic cooperation and a security guarantee to North Korea in exchange for Pyongyang 's continued effort on denuclearization negotiations . " Koh Yu-hwan , a North Korean studies professor at Dongguk University in Seoul , agreed that Xi had facilitated the Trump – Kim meeting . Japanese Prime Minister Shinzō Abe said that " Japan has been supporting the U.S.-North Korea negotiation process since their Singapore meeting . " Pope Francis praised the summit as " a step further in the walk of peace " for the Korean Peninsula and " the entire world . "
