Excellent. I think the big statement here by Putin is that Russia is moving away from the buy-sell military relationship with China to co-development. It's a type of acknowledgement, that China has advanced military technology that Russia desires. For obvious reasons, Russia doesn't want to buy Chinese weapons directly. So the best way forward is to co-develop stuff with China.
So for example, China and Russia might wanna co-develop a new heavy HALE drone. China has the expertise, while Russia would want the ToT, and manufacturing know-how. It would be nice if the cooperation could also extend to major naval vessels and nuclear submarines. Russia needs newer capital ships, and China could use an additional boost in nuclear submarine tech. Since there is that AUKUS deal by the other side already, such a deal not that unthinkable.
P.S.: In my opinion they should insert a special clause in any co-development deals between China and Russia. No sales or ToT allowed to any 3rd countries that have problems with China or Russia. No matter how friendly they are to either of them. So no sales or ToT allowed to India, Vietnam, PH, Turkey, Ukraine, or any other NATO nations or partners. Ideally, these co-developed technologies should only stay between Russia and China only.
