This thesis presents the Chinese and European competition laws on abuse of dominant position. The thesis starts with an introduction, and goes on to present the purpose of the study, which is to determine the similarities and differences between the Chinese and European prohibitions on ADP.       After the introductory part, consisting of background, method, material and previos research, the respective prohibitions are described in different aspects. The aspects are namely system, purpose, scope of application, what constitutes dominance and what constitutes abuse. Thereafter, the two prohibitions are compared. In the comparison, similarities are presented such as similar purposes, similar scope of application, very similar in what constitutes a dominant position and abuse. The systematics however differ more, and so do the rules on extraterritorial application.      In the concluding remarks, the results of the thesis are highlighted and the author shortly analyses the results..
