I've found very little on this subject, I can't seem to re-trade imported resources.
For example in my current game I have one Cocoa at my city Antium giving me 4 amenities and another Cocoa which I bought from China because it was cheap, the report correctly shows I have 2 Cocoa. But when I go to the trade screen it only shows 1 Cocoa (presumably this is Antium's Cocoa?) and if I sell it the trade screen says I have no Cocoa but the report correctly says I have 1 Cocoa at Antium, one Cocoa bought and one Cocoa sold, total one Cocoa.
I waited a turn in case the game needs to update but the second Cocoa never appears in the trade screen.
So the Cocoa I bought from China I've wasted my money because I can't re-trade it?
The first copy of an imported resource does give 4 amenities but surely it can't be that any duplicate resource attained through trade is completely useless?
