Exactly this. Russia was very much part of the 8 nation alliance and committed various atrocities like rape, murder, plunder, arson and destruction of cultural relics. Prior to this they had also threatened China with war and forced her to sign the treaty of Aigun thus gaining control over outer Manchuria and cutting off Chinese access to the Sea of Japan. Later in Soviet years, we again saw numerous skirmishes and murders committed by USSR troops during the Sino-Soviet split. Personally, I believe this is payback for Russia being a mean bully, they are bleeding and killing as usual but this time China is in a very strong and favorable position. Historical grievances should be kept in front of the eyes to gain the most out of this country, resources and increased leverage if not outright territorial concessions. This is not China's war, let the Slavs kill each other, if US acts up threaten them with weapons supply to Russia, play them against each other, this is a wonderful once in a century opportunity to get back at Russia & the West combined, of course be careful not to push Russia away but other than that Russia should be thankful China is a responsible Superpower and won't be upto any mischief in the East while continuing to fill the technology & trade vaccum left by the West. Putin loves to dive deep into history while making his points, he will understand & appreciate China's position. Another bully in the 8 nation alliance not getting enough attention would be pathetic third world failed state India. For them I have no sympathy, should they fall into any precarious situation with Pakistan/ China, China shouldn't hold back at all. It is the one country I decisively advocate going to war against.
