Using archival material from states, international organizations, and business actors, this paper explores how the Association for the Promotion and Protection of Private Foreign Investments (APPI), a transnational business interest association (BIA), liaised with different international institutions to lobby for better foreign investment protection. We zoom in on the United Nations, the Organization for Economic Co-operation and Development, and the World Bank to examine how APPI influenced the global institutional landscape during its heydays from 1958 until 1974. We show that business actors, particularly oil and banking corporations, created APPI as a nimble, efficient alliance that could move faster than existing BIAs. We further demonstrate how companies “forum shop” between different BIAs, and how APPI injected its ideas into the policymaking process, using the framework of the three faces of power. By shedding light on the role private business actors played in foreign investor protection, the paper contributes to a better understanding of the emergence of global economic governance in the second half of the 20th century.

On 24 June 2022, the Contracting Parties of the Energy Charter Treaty (ECT) finalized discussions on the modernization of the treaty. After fifteen rounds of negotiations, an agreement in principle was reached to be adopted by the Energy Charter Conference on 22 November 2022 in Ulaanbaatar, Mongolia.1 The ECT, adopted in 1994, establishes a legal framework that aims to promote international cooperation in the energy sector.2 It has a membership of 53 countries primarily from Europe and Central Asia, as well as the European Union (EU) and the European Atomic Energy Community. In recent years, the ECT attracted widespread public attention due to its impact on states’ environmental and climate policies. Particularly, the treaty’s provisions on investment protection, with investor-to-state dispute settlement (ISDS) at the centre, allow foreign investors in the energy sector to challenge adverse state action before international arbitration and claim compensation for measures affecting their business activities. Fossil fuel investors have increasingly used the ECT to challenge environmental and climate measures, such as phasing out coal-fired power generation, banning offshore oil drilling in coastal areas, and prohibiting gas fracking projects. Such cases have fuelled concerns regarding the abilities of governments to roll-out large-scale climate action. The Intergovernmental Panel on Climate Change (IPCC) has warned that international investment agreements (IIAs) like the ECT could ‘be used by fossil-fuel companies to block national legislation aimed at phasing out the use of their assets’.3 With some of these damage claims running into billions of euros, the ECT enables fossil fuel investors to offload the costs and risks associated with their affected assets onto society at large in the face of necessary climate action. This would go, in the words of the editorial board of the Financial Times, against the ‘heart of the capitalist social contract’ and the ‘ability of markets to deal adequately with the challenge of climate change’.4

Can supranational actors influence domestic policy? In this article, we study how international organizations have sought to shape the contents of domestic laws aimed at protecting foreign investment. Traditionally, the influence of international organizations on public policy has been assumed to run through loan conditionalities. We build on a recent strand of literature indicating that international organizations can also influence public policy through technical assistance. Empirically, we present a cross-sectional mapping of the protection that states offer foreign investors in domestic investment laws, and a mapping of the advisory activities of the three main organizations offering technical assistance on foreign investment laws: the United Nations Conference on Trade and Development, the Organization for Economic Co-operation and Development, and the World Bank. We find that there are significant variations in protection offered under domestic investment laws, and variation in international organizations’ technical assistance over time and across organizations. To explore technical assistance as a causal mechanism for influence on public policy more closely in this field, we conduct a case study of the development of domestic investment legislation in Bosnia and Herzegovina.

Investment arbitration is based on international agreements and operates in parallel to the EU legal and judicial system. Therefore conflicts between EU law and investment protection are possible. These may result from the substantial investment protection standards, but also from the operation of a parallel system of judicial protection. The EU law position on such conflicts will depend on whether the investment agreement was concluded between Member States, between Member States and other countries, or between the EU and other countries.
