The fifth workshop for the project on Bolstering U.S.-South Korean Cooperation to Meet the China Challenge examined how the United States and South Korea should strengthen policy coordination on supply chain resiliency. 

Today is my last day at CFR, which marks the conclusion of over fifteen years of contributions to Asia Unbound. My publications and contributions to CFR remain in archives on the website. 

Summary The U.S.-South Korea alliance has been the cornerstone of bilateral cooperation and the U.S. security presence in the Indo-Pacific region for over seven decades and continues to serve as a model of partnership amid a growing range of challenges. Nevertheless, the rise of exclusive nationalism guided by “America First” or “Korea first” leadership that places national self-interest above alliance-based cooperation on shared challenges represents a point of vulnerability for the relationship. Combined with deepening political polarization in both countries, the cohesion and resilience of the U.S.-South Korea alliance may come under threat. The United States–South Korea Alliance: Why It May Fail and Why It Must Not analyzes the internal and external threats to the alliance. It explores how a weakened U.S.-South Korea alliance could impact the security strategies of both countries and the broader security landscape in Northeast Asia. Additionally, it hypothesizes a future without the U.S.-South Korea alliance, shedding light on its potential impact and implications for U.S. and South Korean security strategies. Based on the analysis, the author concludes by offering valuable recommendations to the United States and South Korea for preserving and sustaining the alliance.

It is November 2024, and a new U.S. president has been elected. You are the speechwriter for the South Korean president, who is concerned about whether the U.S. president will maintain the U.S. alliance commitment toward South Korea. You are tasked with drafting a speech for the South Korean president that will provide security, political, and economic rationales in support of the U.S.-South Korea alliance with the goal of influencing the new U.S. president’s course of action. Based on the lessons and themes learned from the book, what would you highlight in your speech? Policy memo: As the U.S. national security advisor, you play a pivotal role in navigating the complex dynamics of East Asia. This includes addressing the ongoing rivalry between the United States and China, as well as U.S. relations with South Korea, Japan, North Korea, and Taiwan. You are tasked with drafting a policy memo for the U.S. president that outlines an alternative U.S. strategy for managing its alliances in the region amid intensifying tensions between the United States and China and growing concerns regarding a conflict involving Taiwan. The memo should also cover potential consequences should U.S. credibility and commitment deteriorate amidst escalating regional tensions. Negotiation: Imagine a hypothetical situation in which the United States is planning to reduce its military presence in South Korea and Japan. Participants will be divided into three groups, representing the United States, South Korea, and Japan. Ask students to discuss their perspectives on the U.S. plan and address the following topics: North Korea’s nuclear program, prospects for trilateral cooperation among the three countries, changes in the dynamics of U.S.-China competition, and the future of U.S. alliances with the two countries.   Supplementary Materials Victor Cha, The Impossible State: North Korea, Past and Future (New York: Harper Collins, 2013). ‌Victor Cha and Ellen Kim, “Between A Rock and a Hard Place: South Korea’s Strategic Dilemmas with China and the United States,” Asia Policy, no. 21 (2016): 101–22.

On November 14, 2023, the Council on Foreign Relations’ program on U.S.-Korea Policy held an in-person workshop on U.S.-South Korea policy coordination toward China on maritime security.

The fourth workshop for the project on Bolstering U.S.-South Korean Cooperation to Meet the China Challenge examined how the United States and South Korea should strengthen maritime security cooperation.

In order for the United States and South Korea to strengthen their human rights-centered approach toward North Korea, key internal and external obstacles should be addressed. 

Despite the setback in the 2030 World Expo bid, South Korea must maintain its focus on revitalizing Busan to enhance the city’s chances in a potential 2035 bid.

Developments at home and abroad are testing U.S.-South Korea relations.

The envisaged scope and depth of U.S.-South Korean cooperation on next-generation critical and emerging technologies will tie the two countries together in unprecedented ways.
