Air China Cargo has ordered four more Airbus A350 freighters, taking its total commitment for the model to 10 aircraft as Chinese cargo carriers expand and modernize fleets to meet rising international freight demand.

The carrier previously ordered six A350F freighters in November of last year.

"The additional order is an important strategic decision to further optimize our fleet structure and upgrade cargo capacity," Wang Hongyan, vice-president at Air China Cargo, said in a statement, adding that the aircraft would help the company better meet demand in the international air cargo market and support its long-term growth plans.

The deal gives another lift to Airbus as it competes with US rival Boeing in the global freighter market.
