You forgot to cite the most important reason, being that southern Xinjiang area Tarim Basin has as much oil as whole of Saudi Arabia and supplies 30% of China’s oil needs. Destabilising and separating Xinjiang from China will result in an inevitable collapse of the country’s economy. China is on its way to overtake USA as world leader.

USA already has hold of Saudi Arabia and sanctions and forcibly controls Iran. By taking control of Tarim Basin, USA will dictate matters over most of the world’s oil.

If they had to care about Muslims, they would not genocide millions of them in Gitmo or Middle East or South East Asia over the past half century.
