IINA: Moving Beyond the Era of "Rule by Force" —Reshaping the International Order and the Role of Middle Powers

By Koji Sakane, Professor, Director of International Center, Shimane University

The framework of the international order, built up over many years, is facing a crisis. The established "governance system based on internationally agreed-upon rules" is being supplanted by "rule by force," and the international institutions and systems that once played a vital role in maintaining the international order are no longer able to fulfill that function. How should we understand this situation, and shape the framework of the international order moving forward? In this article, I will analyze the current structure of "rule by force" and discuss the role that middle powers—and Japan in particular—should play.

IINA: Why China’s Rare-Earth Leverage Does Not Wear Out

The U.S.-China summit in Washington on September 24, 2026, once again failed to resolve the rare-earth issue. The fact sheet released by the White House after the meeting stated that the two countries “continue to work on U.S. concerns regarding supply chain shortages related to rare earths and other critical minerals, with the goal of ensuring shipment levels return to appropriate levels.” Though nearly a year has passed since the U.S. and China reached a deal in the autumn of 2025, U.S. concerns over Chinese supplies remain unresolved.
