The raw sensitivity of radio telescopes roughly follows a "Moore's law" since the start of modern radio astronomy in 1940s. The construction of the Chinese "mega-science" project, Five-hundredmeter Aperture Spherical radio Telescope (FAST), which is to be commissioned in Sep. of 2016, is the next major step in this rapid progression. This talk will discuss the advantages and science objectives of FAST. I will also introduce our fundamental science program (973) supported by the Ministry of Science and Technology to develop key areas and radio capabilities for the Chinese radio astronomy community, in anticipation of FAST.
