During the Biden administration，it is very likely to adopt a policy of simultaneous dialogue and sanctions with DPRK. In this process，it will focus on strengthening communication and coordination with its allies in order to achieve substantive progress in the “denuclearization” process. Due to the need for economic development and easing external sanctions，DPRK has a strong motivation for dialogue with the United States. As a direct party to the DPRK nuclear issue，ROK will continue to promote the dialogue between the United States and DPRK and the peace process on the Peninsula. The Biden administration’s DPRK policy presents both opportunities and challenges for China. China should actively promote the smooth resolution of the Peninsula issue through promoting Sino-U.S. cooperation and international cooperation. The latter can be based on the “dual track” route.
