I read today that South Korea wants to introduce its soldiers into Ukraine, as well as supply offensive weapons. Naturally, it is necessary for the Northerners to fight back.
So far it's just talks, nothing serious:
We would consider supplying weapons for defensive purposes as part of the step-by-step scenarios, and if it seems they are going too far, we might also consider offensive use

And so far we are talking about just few thousands North Korean troops sent to this war, difficult to see it as big deal. And somehow I'm not sure that they're ready and capable to send number of troops that would be really significant, considering tension with South Korea.
I don't know, I've already seen Ukrainian videos where they present camps for North Korean prisoners of war, so maybe, just maybe.
