I don't think so. Just think. If there will be options, like giving something to the AI, and it will raise the relation points between the 2 nations, that is ok. If you call that 'abuse', than what is your idea about diplomacy?
It is normal to use these ways to improve the relations.
Abusing means, that you are trying to cheat the AI.
We must list all possible abuse situations.

1. Improving the relations with the AI, to use him against others.

I think that this is normal. Everyone did this in the history.
BUT the other AIs must see these moves by the players, they must memorize it.
Example: You are trying to make an alliance with AI 1.
You are improving the relations with AI 1, and finally you are making an alliance with AI 1.
All of the other nations must react somehow: The AIs near your borders should try to make alliances as well, if it is possible. (example)

All little situations can be tweaked like this.
Just list more.
