"When the parties involved in the Korean War stand together and proclaim an end to the War, I believe we can make irreversible progress in denuclearization and usher in an era of complete peace."
An end-of-war declaration on the Korean Peninsula has been South Korean President Moon Jae-in's long and ambitious goal during his presidency.
But his third proposal at UN General Assembly over the weekend called for the involvement of all parties: the two Koreas, the U.S., and China.
But one expert says that there are many hurdles to overcome before that point can be reached.
"All four parties agree on the need for an end-of-war declaration, but it will take some time for all of them to participate after taking care of U.S.-China tensions and the distrust between the North and the U.S."
The Pentagon said on Monday that Washington is open to discussing a possible declaration with the regime but watchers note that's also under certain conditions such as complete denuclearization of the Korean Peninsula.
But it is expected that Pyeongyang will want its own requirements to be met first such Washington easing its sanctions against the North as well as the withdrawal of U.S. troops from the South.
Beijing has long insisted that it should play a role in any end-of-war declaration.
But it is highly unlikely that it would get involved upon Seoul's request.
"No progress made on Washington-Pyeongyang negotiations, and the two Koreas are not even communicating. There's no reason for Beijing to step in to declare an end to the Korean War."
The expert added that the North's recent missile activities and different wants and needs from each party will only impede the peace process on the Korean Peninsula.
