It shows nothing of that sort, but that you have not a clue.i understand your point and you may be correct that only time can tell what the outcome will be on the long run
but have a look at the highlighted sentence in your quote its not about havin a big wallet about having the will to do, in that case russia is willing to spend its limited resoures on R&D while china is busy copying the stuff, reverse engineering is not the same a spendin on r&D
when you reverse engineer you do learn something but you always reverse engineer from something to something means some under county already had the tech before and you are playing catch up,
it shows that your would not invent something new you will only be second best but never the best till the will is there and its clearly not there in case of china
It's either copy and raise our starting baseline or R&D our way up from scratch. Clearly the former is the better option. Then we innovate from there.
Chinese radars in some areas do surpass Russian equivalents. I think OOE's dear comrade Xinhui can elaborate on this; that there are several instances where countries bought Russian missiles with Chinese radars.
