China wouldn't even have a space program if it wasn't for a Chinese scientist who stole the technology from the US: Qian Xuesen, the supposed father of the Chinese space program was a thief.
Every technology that China currently possesses, space, defense, or otherwise (bioweapon tech Chinese Communist Party used to create Covid in Wuhan lab) , it stole from the west, Russia or elsewhere. Of course when you steal stuff, you don't understand it completely and things go wrong, as with this rocket and other Chinese space debris falling to earth, as well as the Covid pandemic that Chinese Communist Party (CCP) gifted to the world.
The smart thing to do would be to shut the doors on China and Chinese people as long it's an authoritarian power run by CCP to protect yourself from the CCP agents/thieves. And most Chinese people in other countries are CCP agents sent there to steal IP.
