Union set up by manufacturers aims to improve air parts quality

China's aviation industry must encourage more private enterprises to promote the development of large jetliners, said an industry leader.

"It takes a long time and a solid industrial foundation for a nation's civil aircraft industry to grow up and become strong. A huge investment, planning and management resolve are helpful, but they are far from enough to build a real, large airliner," Zhang Hui, executive vice-president of AVIC International Holding Corp, told China Daily in an exclusive interview.
