How do you stop institution spread?

[Vampiresbane]

Playing as Oda/Japan and I’ve unlocked Renaissance and Colonialism before anyone in Asia; I want to keep these to myself forever if possible, a very long time if not.

How do I prevent their spread? I hold mainland Japan, not the Ainu island or Ryuku island, and no land in mainland Asia.

Insult Korea; insult Manchu tribes; make sure you have bad opinions towards Asians whom you share a sea tile with, and vice versa such that they won't bother to improve relation with you.

Thanks DB. The reason I ask is there's little to no transparency off the wiki. I've only read the following through reddit:

• Friendly relations allow for institutions to spread faster both through adjacent provinces (same continent, same land mass) and through sea tiles.
• Unfriendly relations slow down spread through adjacent provinces, but don't halt it completely.
• Unfriendly relations prevent institution spread completely through sea tiles.

But I didn't know how accurate this was or if there's even more going on.

If that's all there is to it, I do what you suggested, privateer all the trade nodes around me as well for extra measure (and power projection vs Ming/Korea), take over Ainu so there's no spread through my land connection, and just never take any China mainland territory until I want to go full bore and knee deep into China. Plus if I want to ally any tributaries of China, I pick ones there's no connection to, land or sea.

Don't expect Ming to fall significantly behind in tech even so. Korea or Ming usually develops at least Renaissance eventually, and Ming gets crazy amounts of monarch power through tributaries and meritocracy advisors, so they usually have no trouble keeping up.

When you do decide to go for China you could move your capital out of Asia (e.g. Oceania) so that you can make trade companies out of your new land, as they prevent institution spread. Just make sure that you only take trade company land.

Noted. Though it's year ~1520 and they're roughly 2 techs behind me so super helpful, at least navally for now. Korea and Ming are working on developing certain provinces, but they're no where close to unlocking Renaissance (~25% to 33%).

Make sure you have a negative opinion of anyone you border or share sea zones with. Once their provinces are getting close to having institutions present you can conquer these provinces from their owners, and thus delay them further.

Very interesting. I didn't think about doing something like that. I may/may not take it that far, but it's definitely tips like that I'm looking for.
