After the missed approach, the CX crew declared that they did not have enough fuel for another approach and made a 180 turn to the opposite direction RWY07 for a visual approach.
OK, I can understand a crew getting into such a situation, especially with the pretty lengthy HKG GA and approach procedures.
If it is as reported, I would have thought it more professional (thinking NUTA - Notice, Understand, Think Ahead) to have advised ATC of the situation so that they could build in an extra couple of miles in the approach spacing or whatever to help avoid the GA in the first place.
