What are the factors which determine the AI "wanting your provinces"?

[anomanderus]

I ask because at the current time an AI power ruled by a dynasty whose name could be considered a synonym for incest wants one of my provinces, but I don't even border the country that wants it and it doesn't have a claim either- there is no strategic value for that country having it. It just wants it, apparently.

They toss a coin. But seriously, thats too common, there is often no logic behind it.

Just asking ... is that particular province a trade center ?

What I've noticed:
- Trade centers
- Sometimes provinces in trade nodes they control (which means 75% of your country)
- Provinces in a specific map region
- Provinces that will increase their colonization range ...

I guess it pretty much depends on which country (what ideas) we're taking about.

It seems to be completely random and nonsensical. Russia once broke their alliance with me because they wanted my vassal's provinces.

In Africa.
