I didn’t recognise your question earlier. Perhaps you could be more specific.
That said, when you concede that ‘Islam’s influence is limited in China’, what are you implying? That Islam has other enemies besides Christianity?
No. I am not implying anything. Their influence in China is limited: they are only 1-2% of the population and so it is no noteworthy feat for the Chinese to suppress or even annihilate them. They hold the reigns of power elsewhere so the Chinese move is insignificant in relation to the larger Muslim world.
