China's concern not to be on the wrong side of history is underestimated. On the one hand, losing face is rather unpopular in this part of the world, and on the other, China thinks that it has a date with history (with a capital H) and that this century will be its own. So yes, weakening the West can do Beijing's favours at the moment.
In many ways the war is a mixed blessing for China. On the one hand, it loses the element of surprise that it so desired when undertaking the invasion of Taiwan in the backdrop of a complacent & vaccilating west but on the other hand it gives China the opportunity to closely monitor the situation & draw lessons on how the war is prosecuted by Russia , the extent to which the US is prepared to go for the defense of Ukraine or to permanently damage Russia & the extent of co operation between Europe & the US or the fault lines within in spite of overt signs of co operation.
It also gives Chinese military the opportunity to study Russian tactics & analyse it's performance.
But supporting Vladimir P. in his settling of scores from another era and his errors of judgement could be extremely destructive for China's image in the long run. And the Chinese know this perfectly well. Especially since in the future Sino-Russian relationship over Siberian resources, it is in China's interest to have a politically and militarily weakened interlocutor.
With Russia having done it's worst, China would be waiting for what follows in the aftermath of the war. What are Putin's objectives & when does Putin decide it's time to call off the war ? Does the West abide then by Putin's decision by continuing with existing sanctions & imposing more or does it further escalate issues by supporting an insurgency in Ukraine? Mind you the last part would have a serious impact on all of EU / NATO especially the front line states supporting such measures.
Chinese tussle with the Russians is way off into the future. What does Siberia hold that China desires? If it's minerals it won't be difficult for China to strike a favourable deal with Russia on it's terms given the debilitated position of Russia from now on . If it's land, I refer you to the first sentence of this paragraph & would like to point out that in their list of priorities, Russia is pretty much at the bottom as of today. There are other more pressing issues related to expansion of territory already high up on the agenda.
Ironically Chinese claims on other countries's territory is pretty much from another era too much like Russia's but with weaker claims in so far as the fact goes that there are ethnic Russians in those territories that Russia claims who share the same view as Moscow does which can't be said about China.
It is likely that the more VP gets bogged down, the less he will be supported by China.
Putin is pretty much on his own but in the interest of normalcy being restored China would want peace to return & business as usual to commence ASAP. After all China was & is far more integrated with the world economy particularly the West than Russia ever was or will be. They have much more at stake than Putin or Russia. Putin being bogged down would prolong the conflict & further depress the world economy.
In the interim China is in a much happier place. If Putin stayed put, China would be the focus of Western eyes & the possibility then of further friction couldn't be ruled out. They've got a breather now in much the same way they got a breather when George W Bush decided to target China & there was that infamous Hainan incident immediately after which 9//11 happened & China got a huge reprieve which was to last till the 2nd term of Obummer & his "pivot" for whatever it's worth.
We've exited uncertain times to enter even more uncertainty. Such are the times we live in. Which is why Paddy's simple minded posts are to be looked forward to. They provide a source of diversion & amusement.
