There are compelling arguments that dark matter particles, which are believed to be the dominant form of the matter in the Universe, are weakly interacting massive particles, or WIMPs. Direct searches for WIMPs using various low-energy detectors have been conducted around the globe for over twenty years, with tantalizing results. In this talk, I will introduce a new direct detection experiment, PandaX, in Sichuan, China, currently the deepest underground lab in the world. The experiment uses liquid xenon as the detection medium and is the first ton-scale dark-matter-search experiment under construction. The first stage running of the experiment will take place late this year.
