Rebuilding Trust with Japan
President Lee’s historic visit to Tokyo marked the beginning of a new chapter in Korea–Japan relations. Both leaders agreed to launch a joint consultative body to address common challenges such as declining populations, agricultural sustainability, technological innovation, and disaster response.
They also announced closer cooperation in emerging industries like artificial intelligence, hydrogen energy, and cybersecurity, while reaffirming their commitment to peace on the Korean Peninsula. Expanded youth exchange programs and shuttle diplomacy are designed to build lasting trust between future generations.
For the first time in nearly two decades, a joint statement was issued, emphasizing mutual regret over colonial-era grievances and outlining areas for forward-looking cooperation. While some unresolved historical disputes remain sensitive, the tone was clear: Seoul and Tokyo are determined to reinforce their partnership in the face of regional and global uncertainty.
Preparing for the U.S. Summit
Just days later, President Lee headed to Washington for his first summit with President Trump. This meeting carried high stakes, as the future of the U.S.–South Korea alliance is deeply intertwined with security and economic stability in East Asia.
Key topics included:
- Defense Spending: Washington has demanded that Seoul shoulder a greater share of the costs for U.S. troops stationed in South Korea. Lee sought to strike a balance between alliance obligations and domestic opinion.
- Military Presence: Questions remain about possible troop reductions, raising concerns about deterrence against North Korea.
- Economic Cooperation: South Korea proposed a bold initiative to help rebuild U.S. shipbuilding under a “Make American Shipbuilding Great Again” framework, including multibillion-dollar investments from Korean companies.
- Trade and Tariffs: Seoul pushed for relief on tariffs affecting steel, automobiles, and semiconductors while seeking a more predictable economic relationship with Washington.
- North Korea: Lee emphasized a phased denuclearization roadmap, urging pragmatic engagement despite Pyongyang’s continued defiance.
The summit was not only about immediate policy deals but also about building personal rapport with Trump, whose transactional diplomacy often requires flexibility and concrete concessions.
Balancing China Relations
While strengthening ties with Washington and Tokyo, Seoul is also signaling its desire to stabilize relations with Beijing. South Korea sent an envoy to China to propose deeper economic cooperation and normalize strained ties. This reflects Seoul’s strategy of dual engagement—maintaining its security alliance with the U.S. while ensuring economic stability through strong ties with its largest trading partner.
Strategic Significance for the Region
These back-to-back summits highlight South Korea’s emergence as a proactive regional actor. By improving relations with Japan, reinforcing its alliance with the U.S., and cautiously maintaining ties with China, Seoul is working to reduce vulnerabilities while strengthening its leverage.
The “Trump risk” remains a critical variable, but Seoul’s approach shows a careful calculation: align closely with allies, diversify partnerships, and build resilience against policy unpredictability.
