A big mistake.
China's efforts in space necessarily duplicate that which has gone on before. It seems to me she is proceeding quite rapidly to catch up with the other powers.
It seems as if she has a broad-front space program which is proceeding from milestone to milestone without many mistakes and will shortly have the same capacity as the rest of the space powers.
Of course she has he advantage of access to the technology of those who have gone before, whether legitimately or not.
But the last, the very last thing I'd do is underestimate an Asian country which has set it's national will toward a goal.
