With the development of radio, X-ray and gamma ray astronomy,observation now is covering the whole band of electromagnetic radiation. In the radio band, a lot of research interest lies in the millimeter and sub-millimeter wavelength range, requiring new and more powerful observing facilities.

This paper reviews current projects and new initiatives for radio telescopes, including telescopes working at the millimeter and sub-millimeter wavelength bands. The paper also describes key technologies and special considerations in new telescope design, such as surface accuracy,thermal control and other issues. Finally the paper lists all current radio telescopeprograms in China.
