China's space capabilities worry U.S.
By Karin Zeitvogel, Agence France-Presse February 5, 2011


China is developing "counterspace" weapons that could shoot down satellites or jam signals, a Pentagon official said Friday as the United States unveiled a 10-year strategy for security in space.

"The investment China is putting into counterspace capabilities is a matter of concern to us," deputy secretary of defence for space policy Gregory Schulte told reporters as the defence and intelligence communities released their 10-year National Security Space Strategy (NSSS).

The NSSS marks a huge shift from past practice, charting a 10-year path in space to make the United States "more resilient" and able to defend its assets in a dramatically more crowded, competitive, challenging and sometimes hostile environment, Schulte said.

"Space is no longer the preserve of the U.S. and the Soviet Union, at the time in which we could operate with impunity," Schulte said. "There are more competitors, more countries that are launching satellites ... and we increasingly have to worry about countries developing counterspace capabilities that can be used against the peaceful use of space. China is at the forefront of the development of those capabilities."

U.S. concerns over China's space activities have led Defence Secretary Robert Gates to seek to include space in the stability dialogue with the Chinese, Schulte said.

In 2007, China shot down one of its own weather satellites using a medium-range ground missile.
