Uniquely there isn't anything in the game, or on the board, to negotiate other than cooperation. You're not trading corn, or loaning money, or anything. Even "positioning" of pieces doesn't matter because you need allies to do anything, and you'll lose any position without allies; you can't build a fort or get a bonus by holding Indonesia. It's just 'please trust me' and 'please be trustworthy'.
