I sincerely don't believe you have researched your history well enough; and I'm trying to sound as nice as possible when pointing out this fact. You don't just throw in entire civilizations as having racist views (at least in the terms that we think of today, according to skin color). AFAIK the Chinese did consider anyone living outside Mainland China as "barbarians" but to a great extent, it was true (Turkic, Mongols living on the border etc.). They considered Ancient Indians in high regard (specifically I believe due to the Buddha being born in India) and the many Chinese travelers through India have left a well documented account of their travels which are one of the most important sources for historic event during this time. Japan has mostly been a self-contained country, occasionally fighting with Chinese until the Meiji Restoration and the Rise of the Japanese Armed Forces, which was late 19th century. One could credibly argue the racist views they picked up were as a direct result of aping the Western Powers that held similar views during this time period. I'm not familiar enough with Nepalese history to even know what you are talking about. Modern Racism is certainly a European invention, specifically brought about by European colonial interests.
