Initially, the aircraft was to feature many parts manufactured in the United States, including Garrett TFE-731 engine and several cockpit displays along with communication and avionics systems, but due to political developments and an embargo from the US at the end of the 1980s following the Tiananmen Square protests of 1989, other suppliers had to be used. The first prototype was built in 1989, with the first flight taking place on 21 November 1990 by Chief Test Pilot Col Yang Yao (). Flight testing continued from 1991 to 1993 by a Flight Test Team consisting of four Chinese and two Pakistani pilots.
