An International Crisis Group panel discussion, scheduled for March 23, 2026, at the International House of Japan in Tokyo, will examine evolving security arrangements in the Indo-Pacific region and the reassessment of U.S. Alliances by key partners, according to an event announcement released Friday.
The panel, featuring analysts from the International Crisis Group and moderated by Professor Ken Jimbo of Keio University, will focus on the defense postures of Australia, Japan, South Korea, and the Philippines. Speakers include Huong Le Thu, Deputy Director of the Asia Program at Crisis Group. Matthew Wheeler, Senior Analyst for Southeast Asia; Christopher Green, Senior Consultant for the Korean Peninsula; and Georgi Engelbrecht, Senior Analyst for the Philippines.
The discussion comes as regional powers increasingly evaluate their reliance on U.S. Security guarantees and explore independent deterrence capabilities. This shift is driven by changing power dynamics and a perceived need to adapt to an evolving security landscape, particularly concerning instability in the South and East China Seas, the Taiwan Strait, and the Korean peninsula. A January 2025 commentary from the Japan Foreign Institute noted that Australia, Japan, and South Korea share concerns about a deteriorating security environment in the Indo-Pacific.
Recent activity suggests a growing interest in trilateral cooperation between Australia, Japan, and South Korea, potentially as a complement to existing U.S.-led security architectures. The United States Studies Centre hosted an inaugural Track 1.5 Trilateral Dialogue between representatives of the three nations in June 2024, designed to advance policy debate on shared strategic objectives. This dialogue built upon existing partnerships, including Australia’s Comprehensive Strategic Partnership with South Korea and Special Strategic Partnership with Japan, as well as recent security cooperation declarations and improved relations between Japan and South Korea.
The potential for an Australia-Japan-Korea trilateral grouping has been discussed since at least 2014, initially proposed as a way to bolster Australia’s interests during the U.S. Rebalance to Asia. More recently, concerns about the potential impact of a second Trump administration have spurred efforts to strengthen minilateral arrangements independent of the United States, according to a report from International Affairs.
Australia is also facing pressure to reassess its energy ties with Japan and South Korea, particularly regarding liquefied natural gas (LNG) exports, as it seeks to position itself as a regional climate leader. This dynamic adds another layer of complexity to the evolving security landscape.
The International Crisis Group panel discussion will be held in English. No further events or statements from the participating organizations have been publicly announced as of Friday, February 27, 2026.
