Since the establishment of the GATT in 1947 and the WTO multilateral trading system in 1995, trade liberalization has led to an increase in global trade and the internationalization of production through global supply chains. In recent years, however, as non-trade values including national security, labor rights, and environmental protection have become important considerations, supply chains have become an end in themselves rather than a means of pursuing efficiency. Additionally, major trading partners such as the U.S, the EU, and China have sought to regulate global supply chain by leveraging market access to their domestic markets or critical minerals. The proliferation of such unilateral measures has posed significant challenges, as traditional WTO/FTA trade rules have failed to effectively address these new regulatory dynamics. The increasing compliance costs for companies, stemming from emerging supply chain regulations, are exacerbated by the legal constraints and loopholes in existing international trade frameworks, despite previously promised market access in multilateral and bilateral agreements. Against this backdrop, this Brief reviews the current state of disciplines in bilateral and multilateral trade rules and disciplines, with a particular focus on unilateral supply chain regulations. It will explore the critical minerals sector in light of recent sector-specific agreements and arrangements, including the IPEF Supply Chain Agreement, the U.S.-Japan Critical Minerals Agreement or “CMA”, and the EU's Strategic Partnership. While many supply chain issues are emerging in relation to various non-trade values, the critical minerals sector has been the first to see the emergence of more flexible and pragmatic sector-specific agreements and MoUs that depart from the traditional FTA model. This is likely due to the fact that the security of mineral resources is crucial to the competitiveness of domestic industries in many countries. Moreover, the recent trend of resource-owning countries requiring foreign and foreign-owned mining companies to uphold environmental and labor rights during the mineral extraction process has led to the emergence of new ESG (Environmental, Social, and Governance) obligations. The ability to address these elements in a stand-alone agreements or MoUs specific to critical minerals—rather than within the framework of a traditional FTA—marks a key strength of this approach. The evolution of these agreements, especially in the critical minerals sector, is of particular relevance to Korea. As the country faces increasing reliance on the global supply of critical minerals and is deeply impacted by evolving international regulations, it is crucial for Korea to explore its own strategy for securing access to these resources. This Brief will focus on the development of Korea's critical mineral strategy, while drawing the lessons from international agreements.
