Given the fiasco with the CR929, I very much doubt that would happen. Id imagine that they would take the opportunity to expand military industrial plants for their domestic weaponry instead and expand their drone production capabilities. They have a saying in Russia from Tsar Alexander III: “Russia has only two allies: the army and the navy”. I strongly doubt that they would want to rely on a foreign nation for weaponry.
The only thing stopping Russia from buying Chinese weapons is Russian pride, and I think the Ukraine war has knocked a lot of that unwarranted pride out of them these last few years.
Russia is winning on the battlefield. Slowly and at higher cost than it was bargaining for, but not so slowly and costly it cannot afford to just grind out a win through sheer stubbornness. And if Russia really cannot master its pride even now, then that’s what they will do. There is no need for a Minsk 3.0 break, which works against the Russians if they want to grind out a solo win.
But accepting Minsk 3 and doing what Ukraine did during Minsk 2 has a nice ironic twist that I think would appeal to Russians.
And it’s not like they need to buy the whole Chinese arms catalogue. Just a few key purchases could really turbocharge their combat effectiveness, and the best part is that if they really wanted to, they can buy Chinese platforms with legacy Russian/soviet roots and just paint them the same if they really wanted to downplay arms purchases from China.
How many people can tell a J16 apart from a Su30? Or KJ2000s from A50s? Those two purchases alone would be a massive force multiplier for the Russians. But they can also do a radar and avionics upgrade for their home built flankers and they are on a completely different level. Throw in some J35s and drones and they are not afraid of taking on the rest of NATO if America can be prevented from making a meaningful contribution.
It’s largely the same with the army. The Russians spent the lion share of their budget on the big toys and neglected all the support assets and paid heavily for it. But a modest number of key systems being brought up will plug those gaps and allow the Russian army to fight like a modern army again.
