A lot is convergent evolution - a particular engineering problem has many solutions, but they tend to have distinct familial resemblances. Not that they don't copy things too - or at least, "draw inspiration" whenever they can.
The point is though, that China is re-capitulating work done in the US and elsewhere over the last 40 years.
They're serious, and are playing a long-term game. Still a long way behind, but unlike the USA, their space programme is not primarily a device for distributing pork to congressional districts. Some useful, practical products are expected, not ever more "design studies" and on-again off-again project cancellations.
