China says it has informed some countries of anti-satellite missile test

China acknowledged firing an anti-satellite missile but said Tuesday that it had informed the United States and Japan of the weapons test and was opposed to any arms race in space.

Both Washington and Tokyo have expressed concern over the Jan. 11 test in which China used a missile to shoot down one of its own old weather satellites. Both countries criticized the test as a step toward militarizing outer space and demanded explanations from Beijing.

In China's first public comment about the test, Foreign Ministry spokesman Liu Jianchao said Beijing has shown a "responsible attitude" by offering explanations to the U.S. and Japan and insisted Beijing has all along "upheld the peaceful use of outer space."

Foreign Ministry spokesman Liu Jianchao said China has never and will not participate in any outer space arms race.

"The test is not targeted at any country and will not threaten any country," Liu said.

Japan, Britain and Australia among other countries also were concerned that debris caused by the test could scatter and strike other satellites orbiting the earth.

Because China's weather satellites would travel at about the same altitude as U.S. spy satellites, analysts also said the test represented an indirect threat to U.S. defense systems.

Foreign Ministry officials told U.S. Assistant Secretary of State Christopher Hill about the test in a weekend meeting in Beijing.

Hill, who heads the State Department's East Asia bureau, told the Chinese they should be more transparent about their military activities and their defense budget to "avoid any sort of misunderstandings, not only with the United States, but other countries around the world," State Department spokesman Sean McCormack said Monday in Washington.

China is listed as a country of highest concern for the United States, along with North Korea and Iran, in potential for development of weapons of mass destruction.

While Beijing has worked with the United States to induce Pyongyang to dismantle its nuclear weapons program, it also maintains cordial diplomatic and trade relations with some of the world's most repressive countries including Sudan, Zimbabwe and Myanmar.

The test also comes as ties between Japan and China remain precarious because of ongoing disputes over territorial issues, use of maritime resources and interpretations of wartime history.

Chinese military modernization has been a key security concern in Japan, a top U.S. ally in Asia.

Beijing has repeatedly pledged peaceful development of its army — the world's largest — but has caused unease among its neighbors by announcing double-digit military spending increases nearly every year since the early 1990s.

It has spent heavily on beefing up its arsenal with submarines, jet fighters and other high-tech weapons.

A report issued last month by the State Council, China's cabinet, said the Air Force was giving priority to the development of new fighters as well as air and missile defense weapons.
