Air China will resume its flights from Gatwick to Beijing next summer.
The airline will reintroduce the four times a week service on 30 March 2014 using an Airbus A330-200.
The carrier initially launched the service in May 2012 but is yet to be offered year-round.
"Air China regards London as an important global market, and the economic and tourism prospects for China and the UK are positive. We are therefore pleased to reintroduce services to London Gatwick with whom we are developing a good strategic partnership," said Wang Mingyuan, SVP and chairman of Air China's Commercial Committee.
Stewart Wingate, CEO of Gatwick Airport added: "The London Gatwick-Beijing route has proved popular since its inception in May last year and so I am very pleased that Air China has decided to continue operating this service into next summer."
