What was the major impact of Alexander the Great on Eastern Civilization?

Alexander the Great's main impact on Eastern civilization was that, by conquering the Persian Empire, he introduced Greek civilization and culture into east Asia (and the other way around). Greek influences can be seen throughout Central Asia in sculptures, temples, amphitheaters, and other places. Since the Persian Empire sat astride the trade routes that connected India, China, and elsewhere on the vast continent, his conquests brought Asian goods into Mediterranean markets to a far greater extent than ever before. The culture that resulted from this confluence of civilizations was known as "Hellenistic," and it encompassed the entire Mediterranean basin, the Fertile Crescent, and beyond. This period lasted until the final conquest of the Greek-speaking world by the Romans, who maintained the commercial and economic connections with the Asian world established by Alexander. Alexander the Great's conquests connected Asia and the Mediterranean. Greek learning, religion, and philosophy melded with Indian culture, Chinese culture, and many other cultures with profound consequences for all peoples involved.
