In recent years, the EU has strengthened investment control and review. The EU has formed a triple regulatory framework with the EU Merger Regulation, EU Foreign Direct Investment Screening Regulation and Foreign Subsidy Regulation as the core. The regulatory objects, review factors and regulatory logic in this triple regulatory framework are targeted, restrictive and discriminatory to state-owned enterprises (SOEs). It not only hinders SOEs from investing in the EU market, but also squeezes the space for the application of existing international economic and trade rules and has a negative demonstration effect. Therefore, China should make good use of both domestic and international mechanisms and take effective measures to protect China’s interests in economic development and the legitimate rights and interests of SOEs. At the government level: China should actively use WTO rules and dispute settlement mechanisms; promote the entry into force of the China-EU Comprehensive Agreement on Investment; promote the establishment of international economic rules in line with China’s interests; guide the reform of SOEs with the principle of“competitive neutrality”. At the enterprise level: SOEs should strengthen compliance review and risk prevention; take the EU's public interest as a defense; and seek remedies under EU law.
