U.S. tells China concerned by satellite-killer test

WASHINGTON (Reuters) - The United States, Australia and Canada have voiced concerns to China over the first known satellite-killing test in space in more than 20 years, the White House said on Thursday. 

"The U.S. believes China's development and testing of such weapons is inconsistent with the spirit of cooperation that both countries aspire to in the civil space area," National Security Council spokesman Gordon Johndroe said. "We and other countries have expressed our concern regarding this action to the Chinese."
