In my game, I have founded colonial nation in Caribbean. That colonial nation decided to declare war with a country in Yukatan peninsula and proceed to fully annex them, adding 5 more provinces to Carribbean CN.
How do I ask/get them to give those territories to me? Preferably in non-violent method, thus, no war, no granting independence. I need the trade node in Carribbean and Panama to stay under me.
Edit: I want Yukatan peninsula since it is in Central America region. I want a colonial nation there so that I can get another +1 merchant due to >50% trade power.
Edit2: Also now after Caribbean invaded some native astecs and mayans, their territory has grown, causing even more Liberty Desire. Thus, another reason for me to take those invaded provinces from them.
Best Answer
You can only seize province from classic vassals. You can't do it from minor partners (not your question, but thorough answer), or from CN.
You won't be able to get those provinces peacefully.
The only way I can see, would be to hope for rebels to take back the provinces, so you could attack yourself.
On way to do it (you can't of course help rebels in your CN) would be to take a tons of other provinces in this region, either in the direct control of your CN (it will automatically revert to the CN), or be sure to give it to your CN in the peace deal.
You should be able to give a lot of OverExtension to your CN (especially in mexico area), so they will break under rebels.
But of course, that might goes against your primary objective (giving 15 province to your CN so you can get 5 for yourself later). And because you won't have any control over the rebels, it's still random.
I just thought of another possible solution.
Go to war with one of those south west American nation(Co-Bel everyone) with the help of your CN, of course, and loose the war, giving away your CN lands...
(they might not like it).
Might still count as non-violent (for you, after all, you did not fight).
Yet I think abbabab is right, and you ask the wrong question.
You should not worry about those 5 provinces. You will be able to get other CN and the corresponding merchant in due time.
