North and South Korea Saturday struck different notes as they marked the first anniversary of a summit between their leaders that fuelled a whirlwind of diplomacy which has died down amid deadlock over Pyongyang's denuclearisation.
But one year later, little progress has been made on North Korea's nuclear weapons, with Pyongyang and Washington deadlocked since a second summit between Trump and Kim in Hanoi in February broke down without a deal.
Moon, who brokered the first meeting between the two mercurial leaders, has tried to salvage the diplomacy although the North has remained largely unresponsive.
Since Hanoi, the North has not attended any of the weekly meetings of the heads of their joint liaison office in Kaesong, and has not taken part in other joint projects.
North Korea did not respond to the South's invitation this week for a ceremony later Saturday at Panmunjom -- where Moon and Kim exchanged warm smiles and hugs -- to commemorate their landmark meeting last year.
Instead, the North's Committee for the Peaceful Reunification of the Country, which handles inter-Korean relations, urged Seoul Saturday to take "more active measures" to improve ties.
The Kim-Moon summit a year ago had restarted the "ticking of the reunification clock", it said, but the US was pressuring Seoul to lock steps in their approach towards the nuclear-armed North.
"A grave situation is being created that may see a return to the past of reaching catastrophe in the thickening dangers of war," it said in a lengthy statement carried by the official Korean Central News Agency (KCNA).
Moon and Kim met three times last year -- including a second impromptu encounter after Trump threatened to cancel the Singapore summit just weeks before it was due.
But exchanges between Seoul and Pyongyang have significantly decreased since the failure to reach agreement in Hanoi.
A commentary carried by the South's conservative Dong-A Ilbo newspaper Saturday noted that inter-Korean relations have returned to the "old pattern" where Seoul unilaterally tries to engage Pyongyang despite being repeatedly snubbed by its neighbour.
"A year ago, the North Korean leader appeared to listen attentively to the words of President Moon on the footbridge (at Panmunjom), but now he is blatantly ignoring the South," the paper said.
"The celebration event held only by South Korea today presents both dream and reality of the first anniversary," it added.
Kim slammed the South in a speech to his country's rubber stamp legislature earlier this month, saying it should not "pose as a meddlesome 'mediator' and 'facilitator'" between the US and the North.
At his first summit with Russian President Vladimir Putin this week, Kim accused the US of acting in "bad faith" in Hanoi and warned the situation "may return to its original state".
