There is no mention of WB, Gaza or Middle East for that matter. The convention defines as illegal the population transfers when the authority passed from the original legal power to the occupying power. The UNSC resolutions dealing with Israeli occupation decreed that the 4-th Geneva applies to the Territories for the reasons of protection from belligerent occupation of local population.

However, it is pretty clear that you are not one of the legal experts.
