No, I just checked. He's not at war with anyone, and there are no free cities anywhere near him. I'm clearly getting the XP bonuses from the Dutch action.
Funny when I clicked on Wilhemina, she hates everyone except me. Probably because they aren't sending her trade routes. Cranky old bat. She has denounced every single civ except me.
I also checked on my military alliance with India, it's only level 2, and he's not at war with anyone. Level 2 doesn't give shared XP or anything.
I could have conquered that free city, but I was waiting for it to flip to me naturally. I would have eventually got it, but the game ended before then (and someone neutralized my governor Amani as well).
