Using this exploit, I can drain all the AI of all their gold and gold per turn. The AI seems to place a higher value on acquiring a strategic resource they have never seen before than selling it once they have it, allowing me to make a decent gold per turn margin by flipping the resources back and forth between the same AI. In this case, I had to trade a minimum of 22 coal, because any less would trigger the "I cannot accept this deal under any circumstances response." Likewise, when trading the AI this strategic resource when they have none in their stockpile, they will give a high rate of gold per turn for each additional resource up to this quantity of 22 resources. I think a simple fix would be to trigger the ""I cannot accept this deal under any circumstances response" when I try to take a quantity of strategic resource such that I reduce their stockpile below this threshold (of 22 coal in this case). This is the way that diplomatic favor works; if I try to take to much diplomatic favor the AI gives the "under no circumstances" response. Strategic resources only do this when their stockpile is below that threshold; above it an I can take it all, breaking the game. I'm running an unmodded version of the Anthology Edition with all DLC enabled.

Welcome to Civfanatics :)

The exploit you are describing feets on several trade issues and flaws around strategic ressources (already itself questionable strict AI purchase limits at 40/22/62 for the ressources Iron+Horses+Niter/Coal+Oil+Aluminium/Uranium, willingness to pay double when starting with an empty storage, selling everything for cheap when starting from beyond the purchase limit...and Uranium being extra broken with extreme price when trading in small chunks). I have reported them in the past here:
