It is of course of great concern that this has happened for the second time in a few months. Let's not forget though that even if HKA had continued the take off it would have easily cleared the jumbo by maybe a 1000ft. Even with an engine failure it should have cleared it.
In China I've noticed that crossings tend to be done at the runway ends now following the near miss in SHA in order to reduce the risk when a conflicting clearance is given.
