Protectorates and trade/resupply?

[Kekkonen]

I've reached the point in my first "real" SE IV game where I'm thinking of making the neighboring neutral empire my protectorate. I now have a non-aggression treaty with them; if I manage to make them my protectorate, can I propose a separate trade treaty to them? And what about resupply, can I use their planets as supply base?

[Fyron]

I would assume that Protectorate allows resupplying. Check the in-game help menu (F1 key).

You can only have 1 treaty at a time with an empire. You can not make a Protectorate and a Trade Alliance with the same empire at the same time.

I'm not sure the in-game help had anything on resupply. I agree it would be a little odd if you couldn't do it at your protectorate -- "We expect you guys to fight and die for us, but please go somewhere else for gas" doesn't sound like something you'd say to an empire several times more powerful than yours, be it friendly or not. (Of course, I could always colonize a small planet or a moon in their system and make it a supply depot, but I assume this will piss them off.)

Turn off the option to claim new systems automatically. As long as you don't claim their system, they have a good chance of not noticing and getting upset.

protectorate and submissive(?)... those two treaties,
the weaker one pays the powerhouse a duty for their protection (when done right). there is trade going on with those, but it is one sided.

The empire that offers the treaty is the Protector or Subjugator (the "stronger" empire). The empire that accepts the treaty is the one that is Protected or Subjugated (the "weaker" empire).
