In Legends I seem to recall a new feature being that diplomacy is planned ahead by the AI. If its an untrusty race, maybe it won't sign a treaty with you because that would boost your economy, and ultimately it plans to stab you in the back.
Edit: But more likely +20 isn't enough for an unfriendly race to sign.
Thats plain stupid of the AI...
Actually not signing treaty with everyone who asks is not stupid. It would be more intelligent to to sign treaties with those who are no threat and no competition to you. Signing treaties with the other superpowers may benefit your economy, but it might benefit theirs more, especially if they have a rare resource.
The ideal situation would be to find which of the other superpowers who might challenge you for victory is having a spot of bother with another superpower, refuse to trade with them but trade with their rival. You've isolated their economy, now if war breaks out between the two its time to strike. Of course the AI doesn't think like this, but my point is its only beneficial to sign a treaty with someone who:
a) isn't a threat or rival, (I'm not talking about your relationship, but their relative power compared to yours)
b) won't benefit more from the treaty than you
