Nanoscience and Nanotechnology (NT) are emerging fields of science and technology that are witnessing the emergence of an increasing number of new ideas and applications. Many states are seriously looking at military applications of this technology. This paper analyses the impact of NT on defence and looks at its current and futuristic applicability for military purposes, as well as their likely impact on arms control.

As part of its peaceful rise strategy, China has made resolute investments in the field of science and technology. One major aspect of this technological quest has been its investments in space technologies. China's success in this field is remarkable and has brought glory to the nation. However, at the same time, the anti-satellite test (ASAT) undertaken by China, during January 2007, has raised the fears of the weaponization of space.

One important feature of China's outer space policy is to carry out cooperation with all countries. In the cooperation, China pays great attention to the rights and demands of developing countries in the high-technology area. With more actors in outer space, it is necessary and urgent to improve the existing legal system regulating the relations of countries and non-state actors. China's attitude to outer space activities is driven by both domestic and international elements. Development, defence, and technological innovation are the three major goals of China's outer space programmes.
