Ceasefire with AI - not possible?

I have experianced that the AI went to peace again after declaring war ( but that is long time ago not sure if it still applies )

AI normaly declare war when you are a neighbor and get below a certain number in popularity ( same with embargo )

What I did, was I gave it cease fire/peace in the diplomatic section - and thereafter I increased my popularity by attacking dreaded nations, and gave other AIs share map or right of way.

It can take a while, and you need to just recieve their attacks ( and perhaps you need again to change to ceasefire/peace when it attacks you with units after the battle is over )

Good luck.

Thank you. Very helpful.

I joined a game to test it, its actually not possible to change the diplomatic status to peace when you first are at war with the AI. ( like in the old days ) But the other mechanics to make the AI happy are still in place.
