Normally, when you hit a snag in negotiations, the AI will get fed up and end it. If you try to give a deal for the World Map, and try it a few times unsuccessfully, they will break off negotiations due to repeated failures (Let's not discuss this any further).

With what i put in the Spoiler, you can effectively bypass this despite the failed negotiation, and do it over and over till you have Perfect relations with said faction.

Sorry if i'm confusing in the way i explain things, i've never been good at explanations.
