From Reuters report:
China’s destruction of one of its defunct weather satellites in January 2007 showed the Chinese military’s ability to attack satellites, the report said. The United States and former Soviet Union demonstrated that capability in the 1980s.
“The risks inherent in space conflict, where vital U.S. interests are at stake, suggest that preventing space conflict should be a major U.S. security objective,” said the report by technology and security consultant Bruce MacDonald.
[…] China rejected criticism of its 2007 anti-satellite test and Beijing publicly says it opposes the weaponization of space and will not get involved in arms race in space.
Another article in Beijing Review earlier this year suggested steps to prevent space warfare:
The first step in preventing space weaponization is to hold anti-satellite weapon negotiations under the United Nations framework at an earlier date. Then, related international laws and treaties should be signed and efficiently carried out. It would be a good opportunity for countries, including the United States, Russia, China and the European Union, to jointly prevent possible space conflicts and work together so that human beings can enjoy harmony and peace in outer space.
