The Defense Ministry has also refuted an accusation by Western media that China imported U.S.-original military software in the development of its modern military attack helicopter, the Z-10. The spokesman says such accusations are groundless.
Yang Yujun, spokesman of Defense Ministry, said, "China sticks to the principle of self-innovation in our weapon development. We have relied on ourselves in innovation, development and production. All of China's military helicopters and their engines are self-developed. We have their intellectual property right."
