Probably the amount you'd need to tackle a security threat like the ETIM and its attacks that are right inside your country.

20. Welcomes the outcomes of the visit conducted by the General Secretariat's delegation upon invitation from the People's Republic of China; commends the efforts of the People's Republic of China in providing care to its Muslim citizens; and looks forward to further cooperation between the OIC and the People's Republic of China.

...separatism and religious extremism has caused enormous damage to people of all ethnic groups in Xinjiang, which has seriously infringed upon human rights, including right to life, health and development. Faced with the grave challenge of terrorism and extremism, China has undertaken a series of counter-terrorism and deradicalization measures in Xinjiang, including setting up vocational education and training centers. Now safety and security has returned to Xinjiang and the fundamental human rights of people of all ethnic groups there are safeguarded. The past three consecutive years has seen not a single terrorist attack in Xinjiang and people there enjoy a stronger sense of happiness, fulfillment and security. We note with appreciation that human rights are respected and protected in China in the process of counter-terrorism and deradicalization.
