Abstract: Actively taking the opportunity of participating in the Pyeongchang Winter Olympic Games held last February, the Democratic People’s Republic of Korea (DPRK) launched a fierce diplomatic offensive: in March,Kim Jong-un,Chairman of the Korean Workers’ Party,paid a visit to China; in April, the DPRK-ROK summit was held;and the DPRK and the US also announced that they would hold a summit in early June.Kim Jong-un has made positive moves, particularly on the nuclear issue:when visiting China, he affirmed that the DPRK would remain committed to denuclearization of the peninsula; at the Third Plenary Session of the 7th National Congress of the Korean Workers’ Party, he announced the termination of nuclear testing and the intercontinental ballistic missile (ICBM) test launches, as well as the abjuration of the nuclear testing site in the north; and later on, he affirmed with Moon Jae-in, President of the Republic of Korea (ROK), that the common goal of a nuclear free peninsula would be realized through denuclearization. This series of diplomatic moves by the DPRK has taken the world by surprise. The DPRK government’s motivations are both internal and external.In their attempts to preserve and deepen the hard-won peace, and make it a true turning point in their history, the DPRK is obviously faced with multiple challenges, and a lot of work has to be done on the nuclear issue in particular.
