Don't listen it's only stupid propaganda. He's never been in the far east of Russia even though he is russian. There are chinese business everywhere. I was at Blagoveshchensk in 2017, there was around 25 percent chinese citizens, just living there. And the chinese do not do any business with the Russian grandfather for free. All the international support comes with a price. Chinese don't want direct war, they prefer profit if they are allowed. They take over territories slowly and only if they need this territory.

I was in Mongolia recently. They are very concerned about the policy of China, and even more so Russia. That's why they establish ties with democratic countries and arrange a visit from the Pope. They are unlucky to find themselves between two warlike powers and have to maneuver.
