Just pointing out some (among many) points of equipment commonality. I have no idea what Russia has asked for, but there certainly are things China can provide.
The legendary stockpiles of stuff the Soviets accumulated are getting a bit - legendary. All that stuff has a shelf life, and I don’t think either of us knows what state its all in and how much still exists or is still useful. Its been thirty years since the end of the Soviet Union and the massive degradation of its armaments industry. It certainly doesn’t seem like Russia has recovered all that well in this respect.
As in all these things, we will see.
There are maintenance standards for old stuff, the Soviet stuff is pretty much long-lasting.
The point is that we are discussing fake news because both China and Russia denied the talks.
It is basically ridiculous British propaganda, projecting her weaknesses on the Russian military.
