Air China Cargo operates already 7 B744F aircraft. I am sure they have their own trainers. I believe the 4 BCFs ACC is getting are sitting in Victorville anyways. The reason why the trainers are moving to the B777 is obvious. As per the present business plan all B744 pax aircraft will be replaced by 2013/2014 making the B744 a freighter only fleet and of course a smaller fleet. A lot of future conversion courses on the B777, hence the need for C & T from the B744 fleet.
