In western philosophy there was a divergence in both in style, lexicon, and method in the early 20th century that was exasperated by the two world wars. They share common ancestors (Kant basically), but to a certain extent are mutually incomprehensible (an exaggeration, but not exactly untrue). The philosophical world basically divides into Anglophone philosophy (the dominant flavour worldwide) vs everything else which cannot be neatly categorized into a single brand.
Also, while there are non-western traditions none of them have the same degree of professionalisation and size (in terms of practitioners) as western philosophy. Some western philosophers would question whether all that many that do exist are doing the same activity - a curator/historian of philosophy or culture, vs actual philosophers trying to produce original work (again, broad strokes and exaggeration).
