I have an enemy who is crossing my land to trade with another civ. Can I stop them from crossing without going to war?
Answer
No, you cannot prevent another nation’s traders from crossing your territory.
Once you research the Early Empire civic, you gain the ability to enforce borders against military units and allow friendly nations to cross them.
However, traders and religious units are exempt from closed borders, and can wander freely into your territory. See Civ VI Border Rules for more information.
