Its successive refinements and comprehensive transformation have resulted in a tight-knit network of anti-corruption criminal law and a dual system of charges. This system has made a remarkable contribution to combating corruption over the last three decades. More than the outcome of the natural evolution of legal logic, it also involves complex considerations of social transformation and reflects lawmakers＇ expectations of being able to prevent corruption at the institutional level. With the deepening and widening of reform and opening up, China＇s system of anti-corruption charges will inevitably develop towards the thorough abolition of the dual system of charges and the complete restoration of the unitary system.展开更多
