The thing is - without Falcon9 / Starship they really cannot - both China and EU are ~10-20 years (sic) behind SpaceX, and without thousands of satellites on LEO you just cannot have terminal similar to SpaceX's. (And don't get me started on how bad Iris2 is/will be. It's a program that EU has to shut down discussions on how terribly behind we are. The last time I checked, a year ago, EU's plans were to have first Fa…
Anyway, many in these circles thought the USSR would take 20 years to develop the bomb if they ever did. It took 4 years. The hydrogen bomb? The USA tested theirs in 1952. The USSR? 1953.
China now has decades of commitment to long-term projects, an interest in national security and creating an virtuous circle for various industries.
The US banned the export of EUV lithography machiens to China but (IMHO) they made a huge mistake by also banning the best chips. Why was this a mistake? Because it created a captive market for Chinese-made chips.
The Soviet atomic project was helped by espionage and ideology (ie some people believed in the communist project or simply thought it a bad idea that only the US had nuclear weapons). That's just not necessary today. You simply throw some money at a few key researchers and engineers who worked at ASML and you catch up to EUV real fast. I said a couple of years ago China would develop their own EUV processes because they don't want the US to have that control over them. It's a matter of national security. China seems to be 3-5 years away on conservative estimates.
More evidence of this is China not wanting to import NVidia chips despite the ban being lifted [1].
China has the same attitude to having its own launch capability. They've already started testing their own reusable rockets [2]. China has the industrial ecosystem to make everything that goes into a rocket, a captive market for Chinese launches (particularly the Chinese government and military) and the track record to pull this off.
And guess what? China can hire former SpaceX engineers too.
I predict in 5 years these comments doubting China's space ambitions will be instead "well of course that was going to happen".
