This monograph assesses China’s aerospace capabilities and the extent to which China’s participation in commercial aerospace markets and supply chains is contributing to the improvement of those capabilities. It examines China’s commercial aviation manufacturing capabilities, its commercial and military capabilities in space, Chinese government efforts to encourage foreign participation in the development of China’s aerospace industry, transfers of foreign aerospace technology to China, the extent to which U.S. and other foreign aerospace firms depend on supplies from China, and the implications of these issues for U.S. security interests.
