Parallels can be seen between Pyrrhonism and Buddhism. (I just found this if you want to read about the comparison between the two).
I include a brief mention of those parallels in my paper about holy shit. There is a historical possibility that Nāgārjuna (the founder of the Madhyamaka philosophy, one of the primary influences of Mahāyāna Buddhism which represents the majority of practitioners), was directly inspired or influenced by the works of Sextus Empiricus. He may literally have had physical access to translations of those works. Granted (so I think), Pyrrhonism was, in the first place, inspired by a tradition (or traditions) that shared similar philosophical positions as Buddhism, so there is a direct, historical exchange between ancient Greece and India when it comes to skeptical philosophy.
