My issue with this comments here is, do you have any proof? China made a rover with 6 wheels and this means it is stolen? WTF is the "round corners" issue again? I would like to see something more real, like Patent 1234 "Mars rover with metal wheels" then show how China somwhow broke this ridiculous patent. OR show that US rover contains some super secret tech that is also present in China stuff. As far as I know China can send his smartest people in US, EU or other countries to learn advanced stuff then bring them back in have them teach in their universities. Combine that with a large population and a hard working people that have respect for science I can easily see them getting number one in sciences and tech. IMO, keeping things secrets is not a valid long term strategy, look at the Apple new CPU/GPU people are reverse engineering it fast. The only thing Apple can do is put tons of patents (including shit ones) and then FUD everyone with their army of lawyers. There was a post yesterday I think about someone implementing a similar algorithm with the SpaceXs one to vertical land a virtual rocket, see is possible to implement a similar looking thing without sending a commando of guys and steal tech.

A great example is the Chengdu J-20, which was a direct clone of the F-22 using plans stolen from Lockheed Martin. The J-31 is heavily inspired by but not a complete clone of the F-35 because the latter was still under heavy development when the plans were stolen. (https://www.justice.gov/opa/pr/chinese-national-who-conspired-hack-us-defense-contractors-systems-sentenced-46-months https://www.justice.gov/opa/pr/chinese-national-who-conspire...) The J-15 is a clone of the Russian Su-33, reverse engineered from a physical jet they obtained from Ukraine. The only real modifications are the use of lighter composite materials so that the inferior launchers on Chinese carriers could get them in the air.

These examples are all military because private companies are unwilling to publicize their designs were stolen, and the government is unwilling to admit they couldn't protect private industry.

  There are instances of copying. That doesn't mean all successful technologies are copied. Some technologies are harder to independently develop. Supposedly advanced jet engines are really really hard, but space technology strangely less so, because of lower safety requirements. In other words: for the claim "their space technology is stolen", more proof is needed. Just because they copied some other area is not enough proof to say they copied this area.

    The burden of proof is not on a random person on the internet to investigate their space program. I can't prove the technology is stolen, just as much as you can't prove that it isn't. We are not nation-states and don't have the access or resources. But a reasonable person can look at a pattern of behavior and extrapolate. If China in this case was a CS academic that had plagiarized a few papers, HN wouldn't be falling over themselves to give them the benefit of the doubt on their latest work.
