The last decades have seen a number of studies of Neotectonics in China, concerning with geomorphology, recent sediments and tectonics. In this paper, the authors attempt to address this issue from dynamics of tectonic movements. Analysis of present-day crustal motions, distribution of compressional stress axes of the tectonic stress field and their formation conditions suggests that they are characterized by fairly good continuity and coherence as well as consistent orientations. It indicates that the India-Eurasia collision is the primary driving force that determines the recent crustal motions and tectonic stress field in mainland China. Geological data shows, however, that in the Eogene time eastern and western mainland China was under extension and compression respectively that were completely distinct tectonic environments.
