Presidents Moon and Trump agreed that keeping the regime under already imposed sanctions is necessary until the Korean Peninsula is completely denuclearized.<br /> While the two allies share the goal of complete denuclearization,... their approach on how to achieve it isn't in lockstep. <br />Seoul has been pushing to improve ties with Pyeongyang through economic engagement,... while Washington has been pursuing a dual policy of pressure and dialogue which has caused friction between the North and the U.S. <br /><br /> "The meeting between Presidents Moon and Trump was a chance to reopen the possibility of Kim Jong-un visiting Seoul by the years' end-- in the hope that it could give the stalled denuclearization process another push.<br />Shin Se-min, Arirang News, Buenos Aires." <br />
