AVIC I was historically focused on large planes such as bombers (Xian H-6, Xian JH-7), medium commercial planes (ARJ21), or fighter planes (J-7, J-8, J-10, J-11, and JF-17), while AVIC II was focused on smaller planes and helicopters.
Delivery of the Tu-16 to China began in 1958, and the Xi'an Aircraft Industrial Corporation (XAC) produced a copy of it under the Chinese designation Xian H-6.
Originally proposed by Xi'an Aircraft Factory in June 1970 as a 4-engined version of Xian H-6, design begun in February 1971 after the proposal was granted by the state.
