There is a fundamental issue here though.
You're much less likely to innovate, take quantum leap risks and achieve the breakthroughs that put you ahead of your opponents when you run the risk of extreme sanctions and live under significant risk.
I am assuming even the most valued minds in the Chinese military industrial complex have to tread very, very carefully less they feel the wrath of Xi or the party.
Skunks and Phantoms and others don't face the same threats their peers do in the PRC.
A strategy based on IP theft and a culture of fear and suppression is inimical to innovation... and that's delaying them coming up the curve.
All of these new concepts appear pale imitations of western technology.
Chinese engines are ****e, platforms are not truly stealthy, carrier jets can't carry any meaningful payload - the list goes on.
They're very good at jamming from what I understand - and have formidable resources in that respect - enough to really concern the West (as opposed to what is said publicly).
But very little else.
