This was discussed in the Middle East forum a few days after the incident. That thread no longer exists because the page count on threads only goes to 4 pages (the original thread will most likely be on page 9 by now).

It was professionally dealt with and all on-board halon systems worked as designed to extinguish the small fire whilst en route to Urumqi divert.
Job well executed by the crew and a safe outcome for all passengers.
