In my experience, some philosophers and other scholars who have no familiarity with the Chinese tradition are hesitant to study or even discuss it, because they worry that the subject requires some methodology so different from their own that anything they might say would be horribly misguided, and the "entry costs" for acquiring the appropriate methodology are so high in terms of the time and effort required that it is not practically feasible for them to achieve even a rudimentary conversational competence in the area. One strength of Sor-hoon Tan's anthology is that it can help assuage such worries, for it conveniently collects such a wide variety of approaches that, almost regardless of your own orientation, you can find someone in the volume advocating or applying a kindred methodology to the Chinese materials.
