I don't know, Indian religious traditions made their way to the West in the 60s, and today things like yoga are pretty much mainstream. There is also the effect that Indian culture had on British culture in the 19th century: shampoo was brought to the West by an Indian immigrant, not to mention curry, tea, and pyjamas - among others. The effect that Indian culture has had on the West is greater, in my opinion, than the effect Chinese culture has had - though not as strong as that of the African diaspora cultures.
