At present, China is applying to join the Comprehensive and Progressive Agreement for Trans-Pacific Partnership (CPTPP), which places great emphasis on the regulation of state-owned enterprises (SOEs). In terms of rules, there is still a significant gap between China’s SOE legal system and the CPTPP’s SOE provisions, which is a key issue for China’s accession to the CPTPP. In terms of the field, the international community is experiencing a reconstruction of international economic and trade rules, while the domestic society is undergoing a transformation of development models. China can take the following measures to achieve integration with the CPTPP. First, to clarify the competition law concepts contained in the relevant provisions of the Constitution. Second, to define the scope of SOE antitrust exemptions stipulated in the Anti-monopoly Law and expand the fair competition review system. Third, to enact standalone legislation for SOEs, to legalize the classification reform and mixed-ownership reform of SOEs, and to promote SOE competition neutrality reform within the framework of the rule of law.
