I think a large part of why certain regions get get credit for things is because they are better at marketing themselves. Assuming what you say is true about Indias achievements, I would think that they should at least be recognised by their neighbours. If your achievements are only acknowledged by yourself, then racism probably isn't the cause. Purely anecdotal but I've never heard an Indian person talking up their country and pointing to its achievements like you are, whereas people from my small country will not miss an opportunity to tell you how great we are and we claim credit for everything.
