Espionage is fueling China's development of high-end weapons systems

Between its development of fifth-generation fighters and upgraded models of
ballistic missiles, China's military is quickly becoming one of the most

Beijing's willingness to copy and steal other nations' technology.

China has already created prototypes that are remarkably similar to some of

cyber-espionage.
