I am sure if the Russians ask nicely, the Chinese will be willing to supply cannon shells. The Chinese have ample capacity and storage. There would be no announcement like the drone deal with Iran or this thing. How would anyone know the shells are from China?
When it comes to lethal weapons/munitions from China, Russia is too proud to ask, and China is too practical to offer.
Given that this is a real fight and not a cakewalk against a hopelessly outmatch opponent, we have already had many real life examples of covert weapons and munitions supplies being rumbled due to battlefield captures. The latest example are shells from Pakistan going to Ukraine.
If China were to supply Russia with inventory shells, it will only be a matter of time until they are similarly exposed.
Well, at least when it comes to stuff that’s easily identifiable as new and Chinese. I would not be surprised if China has already sent back a lot of the Krasnopol shells and PGMs they purchased from Russia, for ‘routine maintenance’ of course. If the Russians discovers some sort of ‘defect or issue’ with those stocks, and very generously decided to dispose of those old stocks and refund China, or provide newly manufactured replacements many years down the line, well I’m sure China will be very grateful. And if those shells and missiles/bombs should find their way to Ukraine, well firstly, good luck proving it. And even if it can be proven that these were originally sold to China, well China has all the paperwork to prove they were sent back to Russia to be safely disposed of, and are just as shocked that the Russians didn’t do as they promised!
What China could also do is maybe similar to what NATO are offering former Warsaw Pact member countries to replace whatever soviet era stuff they send with newly manufactured replacements. So China can help Russia indirectly by sending on replacement stocks to NK (much less likely in the case of Iran, at least until they normalise relations with the Saudis and rest of the ME) to allow NK to export much of their current and older inventories.
Although all of these ‘reports’ just seems to be minimally changed copy pasta of all the other stories we have been bombarded with since the very start of this war about how the Russians are supposed to be running low on everything from men to tanks to PGMs to cruise missiles to washing machines. I will believe it once I see Iranian drones and NK MLRS confirmed on the battlefields of Ukraine.
