Against the backdrop of growing political, diplomatic, and military- security significance, the strategic value of the Global South has been steadily increasing. The Global South is not an entirely new concept; rather, it constitutes a meta-category encompassing what were previously referred to as the Third World or developing countries, as well as regions sharing geographical commonalities in the Southern Hemisphere and historical experiences of discrimination and structural inequality.

Alongside the rising prominence of the Global South, another critical issue has recently drawn considerable attention in the international community: economic security. This reflects how the economy and security are once again becoming closely linked amid intensifying U.S.–China strategic competition and escalating rivalry over leadership in advanced science and technology. Contemporary discussions of economic security primarily focus on key areas such as supply chain resilience; the enhancement of industrial competitiveness, including the protection of advanced technologies; the prevention of excessive dependence on specific countries through the diversification of trade and investment; and responses to economic coercion (or economic statecraft).

As the importance of both the Global South and economic security has grown, it has become increasingly necessary to conceptualize these two dimensions in an integrated manner and to devise effective policy responses accordingly. Japan and China, both neighboring countries of the Republic of Korea, have already been actively pursuing Global South strategies and linking them closely with their respective economic security policies.

Against this backdrop, this study examines Japan’s and China’s Global South strategies from the perspective of economic security; analyzes the implications of these strategies for Korea’s own Global South strategy; and explores the potential for cooperation among Korea, China, and Japan in areas where economic security policy intersects with Global South strategies.

The analysis suggests that, compared with the Global South strategies of Japan and China, Korea’s approach remains insufficiently systematized. In particular, there appears to be a notable lack of systematic consideration regarding how to formulate and implement a Global South strategy explicitly grounded in economic security concerns. In response, this study offers several policy recommendations.

First, Korea should urgently establish a comprehensive and coherent Global South strategy, supported by a governance framework that brings together actors from government, academia, and the private sector. Policymakers, scholars, and business stakeholders should engage in joint deliberations on how to systematically design and implement a national Global South strategy, culminating in a unified strategic guideline.

Second, the Global South strategy should be closely aligned with economic security considerations and tailored accordingly. Based on a comprehensive assessment of Korea’s economic security environment, detailed analyses are needed to identify priority needs and to determine which Global South countries should be engaged first to strengthen cooperation. In particular, given that stability and progress in inter- Korean relations are crucial for establishing a stable economic security environment, this unique geopolitical context should be actively reflected in the formulation of Korea’s Global South strategy.

Third, institutional frameworks to promote people-to-people exchanges with the Global South should be strengthened. Such exchanges should encompass a wide range of areas, including tourism, international students, and highly skilled talent in science and engineering, and urgent institutional reforms are required to facilitate these interactions.

Fourth, Korea should develop a long-term Global South strategy that can be pursued consistently regardless of changes in political leadership, similar to China’s Belt and Road Initiative and Global Development Initiative (GDI), as well as Japan’s New Policy toward Enhanced Cooperation with Global South Countries.

Along with these implications for Korea’s Global South strategy, it is also necessary to consider cooperation among Korea, China, and Japan. To enhance the effectiveness of their respective Global South policies, the three countries should seek ways to reduce unnecessary competition and expand avenues for mutual cooperation. A representative example is cooperation with African partners. Rather than operating separate and competing platforms for engagement with Africa, the three countries could consider establishing an integrated framework—such as an “Africa + Korea–China–Japan” platform—to pursue more efficient cooperation. However, instead of hastily advancing “Korea–China–Japan + α” cooperation platforms in regions such as Africa or Latin America, a phased approach grounded in a long-term vision would be more appropriate. As an initial area of cooperation, the joint pursuit of secure access to critical minerals—an issue prioritized by all three countries—could be considered.

Finally, it is important to note that trilateral economic security cooperation should not remain confined to institutional or technical dimensions, such as critical mineral supply chains, but should also entail a broader shift in perception. Korea, China, and Japan need to move beyond zero-sum thinking, in which each views the others as competitors or potential threats to national economic security, and instead embrace a win–win perspective that recognizes the possibility of mutual benefit and coexistence. Under such a mindset, the Global South can emerge not as another arena of competition among the three countries, but as a new space for cooperation that generates shared national interests.
