Well I guess China will need to mine (steal) more intellectual property in order to make the space program a little safer.
To be fair, NASA got a lot of help from Russia who are the top-of-the-tree when it comes to rocket engines.
So Chinese space agency do not necessarily get their "secrets" from NASA (or the US for that matter). All they need is for Premier Xi to ask Putin and the "deed is done", Comrade.
