Nah.
You let islam in because your philosophy. Religion and culture have weak points. Bible is full with contradiction in itself. Concept of love and freedom of choice are open your gate for islam. You don't worship your ancestors or family but jew gods. Things like this will never pass gate of perfection of taoism and Buddhism.

Yes. That's why i said you misunderstood to think diversity are bad thing and china don't have it.
Many great man in china history have race mix with arab and Muslims. But china learn from history that closing itself from the world are mistake . Mao close country is mistake. However Chinese don't dumb enough to go full diversity. Because we know taoism. So we balanced the two power between diversity and harmony.
