This article aims to provide an in-depth and comprehensive analysis of PRC Securities Law 2020 which overhauls China’s securities regulatory framework to construct more efficient and transparent capital markets with enhanced investor protection and market integrity. The law constrains regulators’ administrative powers in deciding the outcome of IPOs as well as streamline the securities offering procedure. This article pays attention to key reform initiatives proposed by PRC Securities Law 2020, such as the registration-based IPO system, the enhanced investor protection and compensation regime, the cross-border supervision, and the harsher punishments for securities frauds. It also discusses the latest enforcement cases relating to high-profile financial frauds like the Luckin Coffee scandal which resulted in Luckin Coffee being delisted from NASDAQ in 2020. The analysis in the article is accompanied by relevant US securities law in the same area to offer a comparative angle, which is of interest to practitioners, academics and policymakers in major financial centres.
