If they build the maglev network as fast as the previous generation of fast trains...
Germany developed the maglev train already in 1970. The only system they could ever sell was the rather short Shanghai airport shuttle. If China now managed to succeed better, could that be called industrial espionage???
we basically sold the Transrapid to them didn't we ?
Espionage traditionally requires a bit more effort than just looking at the thing you bought.
Stolen or not, its at least nice to see someone is actually using (or planing on using) it for more than just epcot-esque toy lines (JR-Maglev excluded)
