The United States, Australia and Canada have expressed concern to China over Beijing’s successful test in space last week of a satellite-killing weapon, the White House said.
The official confirmed a report in Aviation Week magazine that US spy agencies have concluded that China conducted a successful test of a satellite-killing weapon on January 11, knocking out an aging Chinese weather satellite with a “kinetic kill vehicle” launched on board a ballistic missile.

The impact occurred at more than 500 miles (800 kilometers) above Earth.
