Top diplomats from South Korea, the US, and Japan held crucial trilateral talks at the APEC Summit, reaffirming regional cooperation amid tensions over trade, North Korea’s missile tests, and Japan’s new leadership under Prime Minister Sanae Takaichi.
the top diplomats from South Korea, the United States, and Japan convened for a trilateral meeting on the sidelines of the Asia-Pacific Economic Cooperation (APEC) gathering on Wednesday, reversing an earlier cancellation due to scheduling conflicts. The South Korean Foreign Ministry confirmed that the meeting took place in a “pull-aside” format after last-minute coordination among the three sides.
The meeting brought together South Korean Foreign Minister Cho Hyun, US Secretary of State Marco Rubio, and Japanese Foreign Minister Toshimitsu Motegi, marking their first formal engagement since Prime Minister Sanae Takaichi’s new government took office in Japan last week. This diplomatic exchange follows recent summit talks between South Korean President Lee Jae Myung and US President Donald Trump, signaling ongoing efforts to sustain trilateral coordination despite shifting political dynamics in the region.
A Meeting That Almost Didn’t Happen
Initially, the South Korean foreign ministry had announced the cancellation of the planned trilateral meeting due to overlapping schedules, as reported by Yonhap News Agency. However, in a sudden reversal, the three diplomats decided to meet informally on the APEC sidelines, a move interpreted as an effort to demonstrate the resilience of their alliance amid growing global challenges.
“The meeting reflects a shared understanding that cooperation among Seoul, Washington, and Tokyo remains indispensable for regional stability,” an unnamed diplomatic source told reporters.
Changing Leadership, Unchanging Priorities
The meeting also comes at a time of political transition in Japan, following Takaichi’s election as the country’s first female prime minister. Her administration’s approach to regional diplomacy is being closely watched, particularly given her hardline views on historical and territorial issues with South Korea.
Observers note that the Seoul-Tokyo relationship could face fresh challenges under Takaichi’s leadership, but both nations have signaled interest in maintaining dialogue. President Lee is scheduled to hold bilateral talks with Takaichi on Thursday, while President Trump already met the new Japanese leader earlier in Tokyo before traveling to Seoul for APEC-related events.
Balancing Trilateral Relations Amid Trade and Security Pressures
The US-led trilateral framework—forged during previous administrations—now faces new tests under President Trump’s second term, marked by renewed “America First” policies and increased tariff pressures on both Asian allies. Analysts suggest that the APEC meeting provided a vital opportunity for the three nations to reaffirm their strategic alignment despite economic frictions.
“The leaders are navigating a complex landscape where trade, defense, and geopolitical stability are deeply intertwined,” noted one regional analyst. “Maintaining trilateral momentum will be essential for addressing security threats like North Korea and ensuring a balanced regional order.”
North Korea and Cybersecurity on the Agenda
Beyond diplomatic optics, the meeting focused on North Korea’s recent missile provocations and emerging cybersecurity threats, particularly Pyongyang’s crypto theft operations. Just a day before the APEC session, North Korea test-fired sea-to-surface strategic cruise missiles into the Yellow Sea, a move widely seen as a provocation ahead of President Trump’s arrival in South Korea.
Earlier in the week, North Korea claimed to have conducted hypersonic missile tests, heightening regional tensions. The three foreign ministers discussed possible coordinated responses and reinforced their commitment to upholding UN sanctions and deterring further aggression from Pyongyang.
No Trilateral Summit—But Dialogue Continues
Although speculation had mounted over a potential trilateral summit among President Lee, President Trump, and Prime Minister Takaichi during the APEC forum, diplomatic sources confirmed that such a meeting was unlikely this week. Nevertheless, Wednesday’s ministerial dialogue underscored a renewed commitment to communication and coordination at all levels.
Outlook: Reaffirming Alliance in Uncertain Times
As Asia grapples with shifting power dynamics, trade protectionism, and North Korea’s ongoing provocations, the resumption of high-level trilateral engagement sends a strong signal of regional solidarity. For Seoul, Tokyo, and Washington, maintaining open channels and shared strategy remains key to countering instability and preserving Indo-Pacific security.

While leadership transitions and domestic politics may alter the tone of relations, the enduring strategic necessity of cooperation among South Korea, the United States, and Japan ensures that dialogue—however informal—will remain at the heart of regional diplomacy.
