The Pyongyang Declaration fell short of addressing the U.S. demands for North Korean denuclearization. It broadly declared that the two nations would work together toward a Korean peninsula “free of nuclear weapons and nuclear threat,” and that the Northern regime would take steps to permanently dismantle nuclear and missile test sites (including Yongbyon, the birthplace of the country’s nuclear program) if the U.S. took “corresponding measures.”

Kim also agreed to welcome “experts of concerned countries” to witness the prospective dismantlement process. However, he made no commitment to provide either a list of the country’s nuclear facilities or a step-by-step timeline for closing them down — a major step many in Washington had hoped to see.

What’s next: Moon is scheduled to brief Trump on the outcome of the Pyongyang summit during his trip for the UN General Assembly next week. Trump has already expressed interest in a follow-up summit with Kim and hailed the Pyongyang developments as “very exciting,” but it remains to be seen whether the Declaration will be sufficient to move the U.S. toward further negotiations — and possibly toward another meeting between Trump and Kim.
