"Over the past year, the situation on the Korean Peninsula has seen important positive changes. The Korean Peninsula problem has got back on dialogue and consultations' track, and the North Korea-South Korea relations have improved significantly. China supports Pyongyang in implementing serious measures toward denuclearization of the Korean Peninsula," Lu added.
The situation on the Korean Peninsula has greatly improved in 2018, with Kim engaging in an active dialogue with both South Korean President Moon Jae-in and Trump. During the landmark Kim-Trump Singapore summit in June 2018, the two leaders agreed that North Korea would make efforts to promote the complete denuclearisation of the peninsula in exchange for the United States and South Korea freezing their military drills as well as the potential removal of US sanctions.
