I did notice on the deplomacy page that my relationship with the two baltic powers is "reserved" (what does that mean?) yet Sweden still attacks Indian ports owned by me. I would love an explanation of this.
The moment your AI ally makes peace with a company, your company does the same.
However, occasionally your opponents still dislike you for what you've done

so they keep on attacking you, hoping you would declare war on them.
If you have any of the MTI stockpiled in your hometown warehouse, use those in the diplomacy screen to "bribe" yourself into better relations with Sweden.
Also, allying with AI isn't really a good idea. It's not something powerplayers do in this game. It costs you resources cause your allies can buy from your ports and also drags you into wars you don't always want to fight.
I have to disagree with this.
Having an ally is occasionally a good idea. For instance when you plan to destroy all other companies.

Often the AI-opponents are too busy to fight my AI-ally to notice I'm capturing / sinking their fleets one at a time. And usually when they do notice, it's too late for them.
Not to mention, by using an AI-ally to help you fight your wars, you keep your ally weaker too, making it easier to destroy it when the time comes to kill your last competition.
Another good reason to have an ally is that you can occasionally exchange some "useless" ports for an Indian Port. That's how I got Bombay in one of my games, by exchanging it for Mozambique, Luanda and Mocha.
And finally, the AI-ally might buy your goods in your ports, but keep in mind that you can buy
their goods in
their ports as well. Making it easier to complete a campaign goal without waging war all the time.
