I think it's not abt China not doing enough to provide education for them. Most of the uyghur choose to go Islamic school and isolate from main stream Chinese education. In fact, in university quota, special number are allocated for minoirity to enter U even they score lower than Hans student. But if China push too hard to force most of them go conventional school then you again have the issue of suppressing minority,right? Yes, CCP do realize the problem are doing more now to combat extremism and what impact some of the unqualify Islamic school Will do to uyghur society in China.
This is the main problem even though the Chinese government has provided a platform for the Uighur community to join mainstream education, they have decided to isolate themselves by only focusing on Islamic studies and there own language. Some how the government must convince and attract the youth to mix with all ethnic groups and at the same time introduce correct teachers to educate issues on Islam. Unfortunately the Uighur communities knowledge on Islam is non-existent and when you have limited expertise on any philosophy the plague of extremism tends to occur. The government needs to create a framework of balance between the two. I mentioned previously that the government has introduced a quota where the allocation of minorities to enter a university with lower marks is applied across China, however this has not translated into jobs for the Uighur community, which creates a new problem of frustrated youths. If the government does push minorities into conventional schools, then in my opinion this is not considered suppressing minority rights, although you can compromise by having both being taught in mainstream schools. In Xinjiang students can then have the choice to learn Islam as a module as well as national curriculum modules. However basic idea is using force will not solve the problem as Operation strike hard is a prime example, therefore use Islamic philosophy against them. One example is that Muslim are never allowed to rise against the rulers of a State, unless the government stops them from practicing Islam and even then you should migrate instead of picking arms.
