I have noticed a bug with the AI trading. Roughly four times per game an AI opponent will offer me a trade and I click 'Accept' and then they reject their own trade offer?!?!
I've found that talking with AI opponents usually doesn't get me very far (they reject most things, even trades that are in their favor, says "impossible" was too frequently). I usually have to sit back and wait for the AI to come to me and make trade offers, offers of friendship, etc. It's kind of funny but one time I offered an AI opponent 'Open Borders' (both parties) and they rejected it ("impossible") and the very next turn they came to me with the exact same offer and I accepted it. Sometimes the AI is just too unwilling to make good deals. One AI opponent was getting beat up pretty badly and I came in and offered a Defensive Pact (I was a lot more powerful than them and we had 'friendship' status as well as 'open borders') and they said "impossible".
Sometimes I will offer the AI 'open borders' and ask for nothing in return (free trade offer) and they say "impossible". I'm usually playing on King or Emperor difficulty levels (not the two hardest - Immortal and Deity). The AI will always accept free gold and resource offers though which is good.
Diplomacy and trade deals need a lot more intelligence.
