There are people in the US, for instance, that are Sinophiles, though it may not be immediately obvious to those outside the country. In addition, the Chinese cultural sphere extends outward to most of East Asia. Meaning you can't make an in depth study of the culture of Korea, Japan, or Vietnam and not be somewhat familiar with the history and culture of China. China is as influential in East Asia as the Roman empire was in Europe, contributing architecture, pottery, writing, vocabulary, civic ethics and religion to all those aformentioned countries.
Secondly, modern China is not a country defined particularly by its religious heritage. It's a secular state that merely tolerates some expression of religion, though certain forms of traditional religion are coming back in popularity and support after several decades of repression during the Cultural Revolution.
Certainly no more than America, and perhaps less so.
What nonsense. Pure nonsense. Clearly you've confused propaganda with actual history.
It's more inward looking but it's model of civilization has always tended to be attractional rather than missionary.
Confucianism and legalism are already viable alternatives to many worldviews that are dying in the west. They've also been exported to plenty of non-Chinese countries in Asia throughout Chinese history. So I very much don't accept your conclusions on this point.
