I think so, because bond is built through daily experience one people have with another. If there isn't coexistence, there can't be bond. Virtual devices can help on this matter, through video calls, but I guess it's not the same thing... It's useful to see the other person when they are far away, but if this distance is constant, at some point the bond won't remain strong like before.

There must be exceptions, though. We can't generalize, especially when we don't know for real what is the reason behind that distance. It can be for negligence, careless or it can be for necessity, like the parent having to work abroad, for an example.
