Maybe the Sand guys were included in the peace treaty, and the Sand is not in position to deny the Leaf anything. Maybe was just a matter of calling them...
I believe the Peace treaty was concluded before Tsunade. And the Leaf demanded compensations for the war, and pretty much all they had was those three.
