China has secretly fired powerful laser weapons designed to disable American spy satellites by "blinding" their sensitive surveillance devices, it was reported yesterday. The hitherto unreported attacks have been kept secret by the Bush administration for fear that it would damage attempts to co-opt China in diplomatic offensives against North Korea and Iran. Sources told the military affairs publication Defense News that there had been a fierce internal battle within Washington over whether to make the attacks public. In the end, the Pentagon's annual assessment of the growing Chinese military build-up barely mentioned the threat... According to senior American officials: "China not only has the capability, but has exercised it." American satellites like the giant Keyhole craft have come under attack "several times" in recent years.
