Abstract: Aim of the high-energy nuclear physics experiments is to investigate the production and evolution properties of a new nuclear matter state − the Quark-Gluon Plasma under the extreme conditions of high temperature and energy density. This study brings the unique insight into understanding the deep structure of the current material world and the properties of the strong nuclear force in such ultra hot and dense multi-particle system. It also provides the important opportunity to explore new physics phenomenons under such extreme conditions. In this paper, the main international high-energy nuclear physics experimental projects that China has participated and their physics goals are briefly outlined. The recent highlights of the achievements on investigating the properties of the Quark-Gluon Plasma and on exploring the new physics phenomenons in high-energy heavy-ion collisions made by China are overviewed. The perspective on the experimental research projects for high-energy nuclear physics to the future is given as well.
