Done per request Yes, I do hope this not needed, as an additional factor to consider against AI. There are no obvious in-game strategies to prevent AI coming to cancel resource deals. ADDED: For the rest of the game I play so far, after Bismark's cancellation, I did not see the same cancel-accept on the same popup. AI won't accept for the same deals immediately. Bismark's cancel&accept may be just one-off somehow.
