Need a pro explanation

Good afternoon. Hands reached the multiplayer civilization. Can someone explain to me the moment why when there are two real players on the map (me + my friend) AI does not try to establish trade with you at all and does not try to diplomacy? When I played single player, the AI ​​constantly approached me with offers of friendship, joint war and offered to buy resources from me for a good babos. And in multiplayer, he is wildly passive and does not really make contact of his own free will. And for this the rate of development of the turtle. No money from trade - no boost to development. Is that how it should be?
