How to add more trade routes to civilization 7
To add more trade routes, you must sign a treaty with other leaders called "Improving Trade Relations." This option will only appear if you have a good relationship with another leader. The duration of the treaty depends on the information in the tooltip.
Signing a treaty requires influence, while the “Improving Trade Relations” treaty requires 100 influence. It may be a considerable expense, but if you only build friendly relationships with one or two leaders, you may still be able to afford it.
However, you will definitely hope to gain some influence in an emergency. For example, if you need to improve your happiness because your city is in rebellion, you can use your influence to host local festivals.
