Yes, Genocide

In addition to detaining millions, and forced reeducation, we now knwo that thousands of mosques in Xinjiang have been destroyed. (Also here)

When you look at actions that indicate genocide and ethnic cleansing, systematic destruction of religious buildings is a pretty clear indicator:

Thousands of mosques in Xinjiang have been damaged or destroyed in just three years, leaving fewer in the region than at any time since the Cultural Revolution, according to a report on Chinese oppression of Muslim minorities.

The revelations are contained in an expansive data project by the Australian Strategic Policy Institute (ASPI), which used satellite imagery and on-the-ground reporting to map the extensive and continuing construction of detention camps and destruction of cultural and religious sites in the north-western region.

The thinktank said Chinese government claims that there were more than 24,000 mosques in Xinjiang and that it was committed to protecting and respecting religious beliefs were not supported by the findings, and estimated that fewer than 15,000 mosques remained standing – with more than half of those damaged to some extent.

“This is the lowest number since the Cultural Revolution, when fewer than 3,000 mosques remained,” the report said.

It found around two-thirds of the area’s mosques were affected, and about 50% of protected cultural sites had been damaged or destroyed, including the total destruction of Ordam mazar (shrine), an ancient site of pilgrimage dating back to the 10th century.

A lot of people will be asking, "What can be done?"

The answer is, "Quite a lot," because while the "Hanification" of outlying regions has been a priority of the Chinese Government since before the founding of the People's Republic of China, this particular case of aggressive genocide is very specifically the initiative of current President Xi Jinping.

An aggressive policy of economic and political isolation, one that applies to all of the Chinese elites, would put pressure on them to change the policy or change the President.
