Although not verified through other sources, the Hong Kong Sing Tao Daily newspaper quoted unnamed Chinese resources in reporting that China is developing a space-based anti-satellite system. According to the report, the concept is to deploy very small "parasitic" satellites called nano-satellites that would attach themselves to satellites and re-main inactive during normal times. Upon activation, these parasitic satellites would destroy the satellite or disrupt its operations. Although the existence of a Chinese parasitic satellite program is uncertain, the existence of micro-satellite programs for data transmission, earth sensing and other programs is well documented. Whether the technology will translate into Chinese ASAT capabilities is not known.

The Secretary of Defense is also concerned that China already may have, or is acquiring, the technology for developing laser radars to track and image satellites. This technology would be of great assistance in targeting orbiting satellites. China also already may have the capability to damage the optical sensors on US systems as they pass over China, and may be developing high-power microwave (HPM) technology to be used against satellites. Additionally, there is speculation China may be researching the use of steel balls to kill a satellite or the use of powder, paint and dust to render a space-based laser ineffective. If developed, these applications also could have an effect on other satellite sensors or solar panels. An additional possibility not mentioned in the literature is use of a nuclear ASAT. China already has such a capability within its ICBM force.
