In 2021, Sungmin Cho wrote, “South Korea’s Taiwan Conundrum,” arguing that Seoul’s complex strategic position makes engagement on questions of involvement over a Taiwan contingency complicated. Five years later, we revisited his arguments.

In your 2021 article, you advocated that Seoul should more actively engage in strategic dialogue with Washington on Taiwan issues. Five years later, how has that dialogue evolved, and what adjustments have been made to South Korea’s strategic thinking regarding involvement in a potential Taiwan contingency based on its relationship with the United States?

Outside the government, debates have shifted considerably. Experts in and out of South Korea now examine Taiwan contingencies in foreign and domestic forums, analyzing scenario models and policy options. Though views differ globally, many analysts conclude that full disengagement from the Taiwan risk would be unwise should the United States intervene. Instead, the most fitting role for Seoul is likely rear‑area support—providing logistics, intelligence, humanitarian aid, or other non‑combat capabilities—rather than front‑line military combat forces.

The public reflects this shift. A June 2025 joint survey by the JoongAng Ilbo and the East Asia Institute found that 87.5 percent of respondents considered Taiwan tensions vital to national security, while only 6.1 percent supported deploying combat troops. Meanwhile, 69.1 percent favored indirect assistance, including humanitarian relief, arms or ammunition, or non‑combat personnel. Strategically, South Korea’s perspective has matured beyond official statements, even though formal commitments on concrete action remain absent.

At the governmental level, Seoul stresses the paramount importance of peace and stability in the Taiwan Strait. Yet the administration has offered no public red lines for a contingency and has not disclosed detailed exchanges with Washington regarding possible responses.
