“President Donald J. Trump of the United States of America and Chairman Kim Jong Un of the State Affairs Commission of the Democratic People’s Republic of Korea have committed to cooperate for the development of new US-DPRK relations and for the promotion of peace, prosperity, and the security of the Korean Peninsula  and of the world”. The document signed in Singapore’s historic summit on June 12 by Donald Trump and Kim Jong Un seems clear: after months of diplomatic ups and downs, threats and rhetorical escalation, the hostilities between the two countries seem to have come to an end. North Korea’s leader “reaffirmed his firm and unwavering commitment to complete denuclearization of the Korean Peninsula”, and Mr. Trump “committed to provide security guarantees of the DPRK.” However, there are still many uncertainties regarding the medium- and long-term effects of this historical meeting: Do involved players have a comparable understanding of denuclearization, security, and peace? What motivated North Korea to initiate a negotiating process, and what does Pyongyang hope to gain from the summit? What does Trump really want to achieve? How will Seoul’s, Japan’s and China’s different interests and strategic outlooks come into play?
