Rolls-Royce said they had won contract worth $1.8 billion from Air China to supply and service 20 aircraft engines.
Earlier this month one of the Qantas airplane (Airbus A380 fitted with Rolls Royce engine) hit by safety concerns after one of its engines exploded in mid-air.
In the latest deal Rolls will supply engines for Airbus A350s and A330s.
Steve Miller, Rolls-Royce's civil aerospace vice president, said "we are very proud that Air China has again put their trust in us" with another contract.
The UK company has been battling to allay concerns about its Trent 900 engine, one of which exploded during a Qantas flight, forcing the Australian airline to ground its fleet of A380 jets.
Rolls-Royce says it has isolated the cause of the engine problem and is fixing the engines.
