Sunfish I doubt It matters, and I doubt QF care either.
The Rapid chinese expansion is coming from Chinese carriers only (Xiaman Air next) I do note either Alan or Jayne quoted a few months ago that China was low yield and they were not overly interested long haul or ex Singapore (Tiger got in early). It's as simple as Chinese Passengers sticking with Chinese Carriers. A lot of group tour/packages are all bundled together ex China, working alongside Chinese carriers. Jetstar is going Cooly to Wuhan, but it's a paid agreement, so they wouldn't last if it was on their own two feet.
China expansion is probaly done for the short/medium and possibly long term for Qantas. Some opportunities to Japan, any expansion will come from Asian carriers. Jetstar Pacific is done (about to get hammered by Vietjet), Jetstar Singapore is done (Scoot/Tiger might pose a problem shortly) which leaves Jetstar Japan (AirAsia about to join the fray).
