This article presents a tenth-anniversary comment on three aspects of antitrust enforcement in China’s chemical industry. It first illustrates the significance of three mega-mergers involving the world’s top six chemical companies, and contrasts the specific treatments of China’s antitrust agency with those of the EU and U.S. authorities. It then reviews new challenges posed by the digital age to the traditional chemical industry in administrative investigations. The article concludes by deciphering the convolute interactions between the antitrust law, contract law, and renewable energy law in civil litigation. The effects on competitive behavior exerted by structural shifts in the chemical industry run through the entire analysis of the article.
