When they added Voice Over IP into the game, it increased the amount of friendly non violent interaction in the game. I myself remember the one time a peace treaty was suggested to me over in game voice,

Foe: "Hey, why are we shooting each other"
Me: "Because we are in Tarkov, in a mall full of psychopaths with guns"
Foe: "But does one of us need to die right here and now."
Me: "I suppose not necessarily."
Foe: "I will drop my gun"
Me: "I will make the promise I will not shoot, I am a man of my word"
Foe: "I will keep my gun equipped then."
Me: "Shall we proceed to emercom checkpoint to exfil with both our heads on?"

Small talk ensued about the game on the way to the checkpoint, I am lucky he didn't have friends and it was not am ambush but thats why i didn't offer to put my gun down because it was his initiative and the burden of doubt is one him for making the proposal. Plan for the worse, hope for the best.
