Russia doesn't have the right to mock anyone after the shambles we have witnessed in Ukraine lolKadyrov mock China for lack of solid respond to US provocation but that's about it.
So far, I think Russia prefer China to keep their economic momentum and able to bail them out of sanction.
Its still mind-blowing to me that they even have face to participate in the Tank Biathlon
Nevermind the equipment gap, at least when China participates in military operations it is cold hearted and decisive
