Yes, I think that the entrance and naturalization of Buddhism in China is the best historical analogy for its entrance into the West - though they are not identical. This is much more the case than into south asia, or se asia, or from China to Korea and Japan, or likewise into Tibet. The main difference being that China was already a very powerful and advanced culture, the regional superpower, whereas the others have tended to be those cultures which took over a huge amount from India in toto. When one takes things in toto, then in some ways, less internal adaptation is needed.
The biggest difference, however, is that where Buddhism in India at that time was the science and religion of the day, from one superpower to another, at present, buddhism is the religion but not the science of several smallish cultures going to a couple of superpowers in the west. Unless of course China suddenly makes Buddhism it's national religion, in which case the 21st century will be a huge rennaisance for Buddhism.
