How do I cancel trade agreements?

[Yohan]

I've been trading iron for silk with the Greeks for a lot more than 20 turns now, and the trade agreement has not come up for review as the manual states. Whenever I'm in a trade agreement that benefits me more than the AI civ, that civ will bring up the agreement for review after 20 turns. But in this situation, the AI gets my iron while I get silk, so the AI is perfectly happy just sitting on the agreement and not saying anything about it. How can I cancel the trade agreement?

You can always goto war.

Of course, if you're more the pacifist type, click on Active at the bottom of the diplomacy screen after you've contacted the civ in question. It'll list all the current agreements and you can alter them by clicking on one.

Thanks! That hit the spot.
