This was announced when Air China first bought into Cathay a couple of years ago. Rumours are that they will indeed take some of the BCFs in the desert in addition to their own order of new twinjet freighters. It has all gone very quiet the last year or so with the whole process caught in Chinese red-tape and the lack of urgency because of the economy. Was surprised to see it mentionned again though. I had thought it had fallen by the wayside.
