What did Kim Jong-Un cancel because some hostile activity by S.Korea/US?

I may not be googling right, but all I’m getting is that Trump pulled out of a summit meeting because of hostility coming from Pyongyang
I found many articles on this, I only skimmed the one I’m linking so don’t fight me about the source

I don’t think Kim Jong Un pulled out of anything I think it was Trump that did.

And then did the Trump camp say that it’s disappointed or something like that?
To quote the article:
After several days during which the president appeared to be signaling that secret negotiations ahead of his planned meeting for June 12 were not going well, he said he was pulling out of the meeting because of the “tremendous anger and open hostility” in a recent statement from Mr Kim. He called it a “missed opportunity” and “truly sad moment in history”.

NK and Kim Jong Un were vocally angry about joint US and S Korea military exercises. NK said that it was disruptive to hold military exercises with peace and denuclearization talks coming up. But they never cancelled anything. Trump did.

Thanks all.

I thought Kim Jong_Un cancelled it and that led some experts in the topic to say something like:
See? That’s what NK has been doing for for a decade…. I had a strong feeling he was going to come up with something to not go through with it Now if I can find articles or video of that.

By the way I remember experts and non experts saying He hasn’t twitted about it??? It’s been 2(or so) days Something like that.

@zenvelo Thank you for remebering and posting, I thought I made it up in my head.
