So now Manchurians are no longer Chinese? Is that what you are saying? Why don’t the Chinese let Manchuria become independent in the 30’s? And why are you holding on to Tibet and XingJiang, the fruits of Qing’s conquest?
One can quibble over the exact time the Manchu dynasty became a Chinese dynasty, but by the time the genocide occurred, it was unquestionably a Chinese dynasty. The soldiers who carried out the genocide were all Han Chinese under the green banner.
