This is the situation. My military is weak, my nation is small, but we have culture and technology. Unfortuately, China has the Great Library. I don't really want a war at this time...
As you can see from the image, the Chinese village (top left) is on the verge of deposing it's overlords. It has nothing I want... not unless there is oil under it
I presume it costs China more to keep the place running that it will ever get out of it - so, maybe it will do China more harm than good to keep the village?
I've already taken one town from them using culture. It had a luxury, so there was good reason.
I don't want to upset the relatively powerful Chinese at the moment, so should I rebuff the rebels or ... what would you do?
Should I expect another chance to win them over with culture, perhaps when China doesn't look so big and scarey?
