It doesn't sound like they've had much in the way of communication even before the conflict started. One one end, it seems Caldera is coveted for its abundance of steel. On the other, Gigas would rather take what it believes is theirs rather than negotiate... This conflict might run deeper than we know.

[ If Caldera stays as stubborn as it is, how are they gonna even convince Gigas of anything? ]

Gigas is an extremely powerful nation-- by the looks of it, they seem to see themselves as an empire. I think we need to be careful how much we discuss with them, or else they might decide to 'reclaim' Union next.
