Wha-huh? Unbelievable! This is the most schizo team ever! 
I would also seriously think about something along the lines of what mh said above. "We're not sending you Literature unless you promise to keep your spies out of our territory." Doesn't seem like a stretch to me, as we offered the trade well before they started mucking around in our territory. Pillaging resources with spies is practically tantamount to a declaration of war anyway. But we don't want the reputation of a team that breaks deals either...
What does everyone think? We've got until next turn to come to some kind of a consensus.
