Yes, there's a CX code on all the Aeroflot services to HKG as of early this year.
CX will start flying the route with their own aircraft though as of mid-2005, probably linking it with, as mentioned earlier, MAN or another European destination, as the route SVO-HKG hardly has enough demand for two carriers to be operating it on a near daily basis, although the SU (6 weekly) flights are doing very well at the moment.
