The Chinese aviation authority will continue following the investigation of Malaysia Airlines Flight MH370, whose disappearance has been declared an accident, an official from the Civil Aviation Administration of China said on Thursday.

"Our investigators will still follow the issue, as the Malaysia government said it will forge ahead with cooperation and assistance from other governments, including China," said Mao Yanfeng, director of the accident investigation department of the CAAC's Aviation Safety Office.

The Chinese authority sent investigators to the location where the aircraft was believed to have disappeared as soon as the air-craft vanished, he said.
