I don't think Rufuk has a clue in the comments section at Sol's shop. Rufuk is unwittingly describing USofA corp. in 1939 before the introduction of UK engine tech and German Hi-tech immediately afterwards to massive human robot systems.
The ChiComms have been given a license to make use of all the west's treasure, remember New York financed all the USSR tech., chest of tech. for a purpose so they do not need to be creative. Only obedient.
Anyway I do have to say that it looks like the ChiComm equivalent of a MilSpec Burt Rutan is happily at work somewhere in the Gobi faking prototypes.
