Pakistan is building, under license, the Chinese Qiang Wei-2 portable anti-aircraft missile. The Pakistan version, known as Anza Mark III, has some cosmetic differences. The missile is very similar in capability to the American Stinger. The Anza Mark III has a range of about five kilometers, and sensors that can defeat many anti-missile systems. China is believed to have used technology stolen from the Stinger for its Qiang Wei line of missiles. For this reason, there is fear that the new Pakistani missile may find its way to terrorists. The new missiles could be stolen, or obtained via bribes, despite the fact that it would be easy to identify the missiles as Pakistani.
