The Moon administration is in desperation mode to get a Korean War peace treaty signed before they office this Spring:
It is the right time to declare an end to the Korean War, as an unprecedentedly favorable environment for the implementation of the declaration has been set up among relevant countries, according to Unification Minister Lee In-young.

In this regard, he also believes the first half of the year could be a “golden time” to make strides in frayed inter-Korean ties and stalled nuclear negotiations between North Korea and the United States, citing a heap of political events in the second half of the year that could disrupt efforts toward Pyongyang-related issues.
Strongly believing such an agreement could serve as a catalyst for negotiations on the denuclearization of North Korea, President Moon Jae-in resurrected his proposal of declaring a formal end to the 1950-53 conflict in a speech at the United Nations last September.
Since then, South Korean and U.S. diplomats have been meeting frequently with each other to discuss the proposal, while National Security Director Suh Hoon also drew support from China following a meeting with top Chinese diplomat Yang Jiechi in December.
Look at what some people want to give up to North Korea to entice them to meet to discuss a peace treaty that is a favorable action towards them anyway:
The lasting silence is fueling speculation that Seoul and Washington should offer something to entice North Korea into responding to the end-of-war issue, and the suspension of combined military drills and partial sanctions relief are being mentioned as possible incentives among others.
You can read more at the link, but the North Koreans want this peace treaty in order to question the legitimacy of U.S. troops stationed in South Korea. If there is peace why are U.S. troops and by extension the UN Command needed?
If the Kim regimes wants a peace treaty they should agree to actions that actually makes it look like they want peace. For example removing all their artillery off of the DMZ would show the seriousness of their peace overtures. If they want peace why do they need artillery to target Seoul and other metropolitan areas?
