The development of economic globalization has driven the emergence of various international trade and investment legal instruments, such as Free Trade Agreements (FTAs), the Investor-State Dispute Settlement (ISDS) mechanism, the International Centre for Settlement of Investment Disputes (ICSID), and the international trade system under the World Trade Organization (WTO). These instruments are essentially designed to create legal certainty for foreign investors, increase international investment flows, and strengthen global economic integration. However, in practice, the existence of international investment law instruments often generates conflicts between the protection of investor interests and the state’s authority to regulate public interests, particularly in the areas of social policy and environmental protection.

In the modern international investment system, host states are bound by various international legal obligations that protect the rights of foreign investors. These protections include guarantees of fair and equitable treatment, protection against expropriation, and the right of investors to bring claims against states through the ISDS mechanism if government policies are considered detrimental to their investments (Sornarajah, 2017). On the one hand, such mechanisms provide legal certainty and security for foreign investors. On the other hand, they are often viewed as limiting the policy space of states in implementing social and environmental regulations in the public interest.

One important case study illustrating the conflict between investor protection and public regulation is Philip Morris Asia Limited v. The Commonwealth of Australia. In this case, the Australian government implemented a plain packaging policy for tobacco products as part of its public health protection strategy. The policy required all cigarette packaging to be plain and devoid of prominent branding elements. Philip Morris subsequently brought a claim against the Australian government through international investment arbitration, arguing that the policy violated its trademark rights and investment protections under a bilateral investment treaty between Australia and Hong Kong (Voon & Mitchell, 2011).

This case illustrates how public regulations aimed at protecting public health can be perceived as a threat to foreign investors’ interests. Although Australia ultimately prevailed in the dispute because the tribunal found it lacked jurisdiction, the arbitration process still generated significant costs and political pressure on the government. This case has given rise to criticism that ISDS mechanisms can be used by multinational corporations to pressure states into limiting social regulation in order to protect business interests.

A second case study can be found in Vattenfall AB v. Germany. The Swedish energy company Vattenfall brought a claim against the German government through ICSID as a result of environmental policies applied to a coal-fired power plant project and later due to Germany’s nuclear energy phase-out policy following the Fukushima disaster. Vattenfall alleged that Germany’s environmental and energy policies had harmed its investments and violated international investment protection standards (Tienhaara, 2009).

This case clearly demonstrates the conflict between the state’s right to protect the environment and the investor’s right to investment protection. The German government was essentially implementing public policy measures for public safety and environmental protection, yet these measures were regarded as violations of investor rights. In such circumstances, the state faces a dilemma between safeguarding public interests and avoiding the risk of costly investment arbitration claims.

These two case studies show that international investment law instruments have a significant influence on social and environmental regulation in host countries. States often experience what is known as regulatory chill, a situation in which governments hesitate to enact certain regulations due to fear of being sued by foreign investors. As a result, protection of public health, the environment, and social rights may be weakened due to pressures from international investment regimes.

In addition, the ISDS mechanism has also faced criticism for being considered insufficiently democratic and lacking accountability. International investment arbitration is generally conducted by private tribunals that do not have adequate public oversight mechanisms. Arbitral decisions often prioritize investor protection over the state’s right to regulate public interests. In some cases, the compensation required to be paid by states to investors has reached billions of dollars, thereby placing a significant financial burden on developing countries (Sassen, 2006).

Nevertheless, international investment law instruments also have certain benefits. Legal protection for investors can increase foreign investor confidence and encourage economic growth through international investment. Developing countries often require foreign investment to support infrastructure development, job creation, and technology transfer. Therefore, the main challenge is not to abolish the international investment system, but to reform it in order to achieve a balance between investor protection and public interest.

In recent years, various reform efforts have emerged regarding international investment dispute settlement mechanisms. One of these is the push to increase transparency in investment arbitration through the UNCITRAL Transparency Rules. In addition, several countries have begun revising or terminating bilateral investment treaties that are considered overly favorable to foreign investors. The European Union has even proposed the establishment of a Multilateral Investment Court as an alternative to the ad hoc arbitration system, which is considered less accountable.

In my view, reform of the ISDS mechanism is essential to ensure that international investment law does not undermine state sovereignty in protecting public interests. States must retain adequate policy space to enact social, health, environmental, and human rights regulations without the excessive risk of being sued by foreign investors. Therefore, international investment agreements should include clauses that explicitly recognize the state’s right to regulate in the public interest.

In addition, investment dispute settlement mechanisms should be made more transparent, participatory, and accountable. Communities affected by investment projects should have opportunities to participate in dispute resolution processes, particularly when disputes concern environmental issues and the social rights of the public. Developing countries must also strengthen their international negotiation capacity to avoid entering into investment agreements that are detrimental to national interests.

Thus, international trade and investment law has a significant impact on social and environmental policymaking in host countries. Instruments such as ISDS and ICSID do provide protection for investors, but they also have the potential to limit state sovereignty in regulating public affairs. Therefore, reform of investment dispute settlement mechanisms is crucial to achieving a balance between legal certainty for investment and the protection of public interests and the environment.
