I think that some factions might have a preset negative modifier though. More precisely, those which are enemies from the start (Russia/Ottomans, Britain/France, etc.).
There are other modifiers to relations such as:

* Historic friendship/enmity
* Trade agreement
* National rulers respected/not respected
* Same government/ different government
* Same religion/ different religion
* Military Alliance
* The enemy of my enemy is my friend
