Korea's Diplomatic Challenge: Navigating a World Split Into Three Blocs

A new framework for understanding global politics has gained attention among international relations experts. Professor John Ikenberry of Princeton University proposed dividing today’s world into three distinct groups: the Global West, the Global East, and the Global South. This model highlights the need for tailored diplomatic strategies in an increasingly complex international landscape. The three groups represent different political and economic alignments. The Global West includes traditional Western nations, while the Global East centres on China, Russia, Iran, and North Korea. The Global South, however, remains harder to define as a single bloc due to shifting alliances and internal rivalries.

This third group consists of developing countries that avoid full alignment with either the West or the East. Major players like India, Indonesia, Brazil, Saudi Arabia, and South Africa are expanding their influence in the global economy. Korea has already encountered the pragmatic priorities of these nations during its bid to host a World Expo. Lee Jae-seung, a professor of international studies at Korea University and head of the Ilmin International Relations Institute, argues that Korea must refine its approach. Trust-based diplomacy should guide relations with the Global West. For the Global East, discreet and behind-the-scenes engagement is key. Meanwhile, visible and active diplomacy will be most effective with the Global South. Balancing these three elements—trust, discretion, and visibility—will shape Korea’s future diplomatic success in this divided world.

The 'three worlds' framework presents both challenges and opportunities for Korea’s foreign policy. As the Global South’s influence grows, adapting strategies to each group’s priorities will be essential. Success depends on deploying the right diplomatic tools in the right context.
