The first Criminal Procedure Law (CPL) of China, issued in 1979, was greatly influenced by the Soviet Criminal Procedure Law in multiple dimensions, including the framework, concepts, principles, and specific institutions. Although the Chinese CPL has changed a lot after three amendments in 1996, 2012 and 2018, respectively, the influence of the Soviet Law can still be noticed in many aspects of the current law. This paper will explore how Soviet Law has shaped Chinese CPL into the way it is. Part I will explore the historical development of Chinese CPL, indicating the close relationship between Chinese law and Soviet Law. Part II will compare Chinese CPLs with the Soviet (and its successor, Russia) CPLs, trying to identify their similarities and differences. Part III will draw some tentative conclusions from the comparison and predict the continuing influence of the Russian law model on Chinese CPL in the future. This paper will primarily rely on comparative study and historical analysis. The legal framework, legal terms, theories, principles, and specific institutions will be examined to illustrate the significant influence of the Soviet Law on Chinese Criminal Procedure Law. This study helps to better understand the evolution of Chinese criminal procedure law and predict its further development more accurately.
