Thank you for your question.
As for when an intervention might happen, I think that Russia will want to spare the Chinese authorities and wait until after the Olympic Games. As for whether military action is likely to be taken, Vladimir Putin is used to surprises. The intervention against Georgia in 2008 took place during the Olympic Games in China. The “five‑day war” in August 2008 took place while the international community's attention was focused on Beijing. Will this scenario be repeated? I can't say, but I would be surprised. I think Russia is trying to be gentle with China because China is a major support of Russia at the moment, so much so that if measures and sanctions are adopted and the energy that Russia provides to European countries is cut off, for example, China would be Russia's best partner to help it bear the economic burden weight of such decisions. I think Russia is trying to spare China and could therefore wait.
Having said that, I would like to come back to something the other speaker said. Russia is a master of misinformation. Arte and Sputnik are the primary vehicles that Russia uses to try to influence the behaviour of Russian Canadians and Canadians in general. It may be that news stations like the CBC will pick up news that is broadcast on Arte, so it's possible that Russia is somewhat behind the support for truckers protesting in Ottawa, indirectly.
