China's space activities raising US satellite security concerns

The United States is concerned about China's expanding ability to disrupt the most sensitive U.S. military and intelligence satellites, as Beijing pursues its expanded ambitions in space, according to multiple sources in the U.S. government and outside space experts.

A classified U.S. intelligence assessment completed late last year analyzed China's increasing activities in space and mapped out the growing vulnerability of U.S. satellites that provide secure military communications, warn about enemy missile launches and provide precise targeting coordinates, said the sources, who were not authorized to speak publicly.
