China has the most rapidly growing space program in the world and continues to develop lasers, satellite jammers and other weapons aimed at the space-based assets of adversaries, a U.S. report said on Friday.
China has also created a "vast ground infrastructure" to build, launch and control satellites, said the U.S. Defense Department's annual report to Congress on military and security issues related to China.
The report marked the latest push by U.S. military officials to highlight increasing threats to U.S. satellite systems. Those concerns prompted the Obama administration to propose $5 billion in extra spending over the next five years to increase the security and resilience of U.S. military and spy satellites.
