According to Flight International 26/11-2/12:-
China Southern is poised to order 4 A330's,which model is unclear.
In addition,6 A319's and 14 more A320's are soon to be order.
All orders are subject to government approval.
This would be the first A330 order for Mainland China,and a breakthrough for Airbus which has not met with great success in widebody sales in China.
Given the A330's,superb cargo capacity and excellent range(-200) this aircraft will be an excellent addition to the rather varied CZ fleet...IMHO.
