Vedic astrology, from my understanding, tho, is actually very similar to "Western astrology" (which really should be looked at, I believe, as Hellenistic astrology, coming from the Greeks), as I believe the lines of transmission of the ideas were significantly increased by the conquests of Alexander the Great.
All that being said, some months ago I learned (to my surprise) that Vedic astrology actually supposedly comes from "Western astrology", or Hellenistic astrology. I had actually previously assumed it was the other way around, as, having many good Indian friends growing up, and having gone to college as well with some of them, it was certainly put into my consciousness that many things we take for granted as "Greek" actually had a largely Indian origin (myths, etc). Some recent research has made me now triple back, and, frankly, I am now uncertain whether this Greek -> Indian transmission is actually what occurred, but, nevertheless, from what I have seen, there seem to be many more similarities between Greek astrology and Indian astrology than between Chinese astrology and either one of them (I have a very poor understanding of Chinese astrology, tho, so, once again, take that with the appropriate grain of salt, as perhaps I don't know what I'm talking about).
Umm.. does that answer your question?
I could probably say more, like about how the concepts and archetypes are essentially the same, I believe, but, while I believe this is largely true (there are things that seem to be accentuated in Vedic astrology, that might not really be as emphasized, or even really prevalent at all, in Western astrology, but these appear to be more like minor cultural variants, whereas the overarching frameworks are more-or-less the same), once again, I'm not expert enough to be completely authoritative on the matter.
