Targeted intel to cause rift between allies.
Sometimes the truth is bitter, and this os the truth.

Here's an answer by a quorian :-
"Chinese people hate Muslims" is definitely an incorrect statement because it purports to speak for all Chinese people.
"Some Chinese people hate Muslims", or better yet "Some Chinese people fear/resent/don't understand/have little sympathy for Muslims" are much more fair statements.
Chinese anti-Muslims voices are strongest on the internet. In this day and age that's true of many forms of hate and bigotry. The internet has a tendency to amplify the loudest, angriest voices and anonymity allows people to say things they wouldn't otherwise. Based on my experience on the Chinese Quora (Zhihu) I can testify that strong anti-Muslim sentiment definitely exists. The reasons are manifold.
Most obvious, there's the spate of recent terrorist attacks in China, which the government has blamed on Muslim Uighurs. The growth of ISIS and the attacks it has coordinated or inspired overseas undoubtedly heighten Chinese peoples' sense of insecurity.
Other reasons for Chinese antipathy towards Muslims have more to do with China's domestic economy, politics, and cultural. Many Chinese are atheist and view allreligions with suspicion, not just Islam. But since Islam is often one of the more visible religions in China (Chinese Muslims can often be identified by their clothing whereas unless they're monks or Tibetans, Buddhists and Daoists cannot).
This may seem trivial, but Chinese people love pork, and view non-pork-eating Muslims with suspicious and resentment. Chinese have complained of being in situations where because Muslims were present they weren't able to eat pork.
Han Chinese complain that minorities in China get favorable treatment, from exceptions to the one child policy (less of an issue now, but was a big issue for years), and affirmative action policies in university admissions and the civil service exam. Granted, this complaint isn't against Muslims in particular, but against all minorities. There's another complaint that's often made, that when Uighurs break the law, the government is too cowardly to punish them. The implication is that Uighurs are above the law, and Chinese people resent that (whether or not that's actually true I'm not qualified to say, but my hunch is that the real situation is a lot more complicated).
My Opinion :-
This resentment is a thing in China without a doubt, mostly aimed at the Uighur population due to the fact that the Government of China gives the minorities greater rights, and many exemptions. The fact that Uighur minority is largely muslim, and that separatist ideas motivated in the name of religion have led to some terrorist attacks in China, the resentment has increased quite a bit. Their resentment, however, for Hui Muslims is much, much less as Hui people are ethnically Chinese and assimilated in culture since ancient China, and cannot be distinguished from ethnic Han people.
It is important to note that the root of this problem is the War on Terror, the war on terror opened up doors to a new era of religious terrorism which spread across the globe including Xinjiang, when the Uighurs started terrorist attacks, the public opinion of Islam and Turks in China went down manifolds to the point of hate, this was non existent before.
But it's still to be important to know that while there is general resentment among the traditional ethnic Athiest Chinese, which is the majority, for Islam and Muslims; their opinion of Pakistan is entirely reversed, they look at the Pakistani people from a completely different lense and see them as friends, and that is reflective in public opinion.
