Question about trading

[lazyboy325]

Well it's wierd, the only option i can do with a nation is "What do you think of... (so and so nations)" but i can't trade or propose deals with them, but i can propose deals with the one nation that i'm at war with. I'm sorta confused, how do i get to the level of trading with nations?

You can't trade particular things without particular technologies.
