Business relations

[matadrox]

Hello! I didn't know where to post this topic, so you can move as it's the wrong place. In general I think it would be useful to have a topic, for general discussions about the game. Back to the point, I wanted to ask what are these business relationships in the game? Are they based on trade only between ai players? Does it refer only and exclusively, to the sale of technology? I sell quite a bit of raw materials and products to AI, but the business relationships do not show any data. Thank you in advance for your interest.
