HONG KONG - China Southern, the country's largest airline, said Tuesday that it would purchase six Boeing B777F cargo planes.

In a statement filed to the Hong Kong stock exchange, China Southern said the catalogue price of each Boeing B777F is $264 million, but the airline's actual purchasing price is "significantly lower than the catalogue price" because of "certain price concessions granted by Boeing".
 
But the company didn't disclose specific price concessions offered by Boeing.

China Southern said the transaction will be paid by cash and partly by financing arrangements with banking institutions.

The six planes will be delivered in stages to China Southern between 2013 and 2015, it said.
