Controlling Wisteria Vine on Trees

Question

Our good neighbor has a beautiful Wisteria vine that has reached the top of his Oak tree and is now reaching our Maple tree with hungry tendrils. The vine is wrapping clockwise. Since I’ve just noticed that the vine is actually established on several high branches of our tree, I am in need of some diplomatic advice on how to manage his pride and joy on our side of the divide. Will I have to cut a good 1/3 of our tree back? Our neighbors are scientists, Asian and take their gardenening most seriously. We would appreciate some info.
