The United States and Japan have signed a landmark agreement to secure the supply of critical minerals and rare earth elements, aiming to reduce their reliance on China and strengthen economic resilience across the Indo-Pacific.
The deal, signed during President Donald Trump’s visit to Tokyo, was described by both nations as a step toward a “golden age” in bilateral relations. Japanese Prime Minister Sanae Takaichi, the country’s first female leader, hosted the signing ceremony at the Akasaka Palace and hailed the partnership as “the greatest alliance in the world.” Trump echoed her remarks, promising continued US support for Japan’s economic and strategic goals.
Part of a Wider Indo-Pacific Strategy
According to the White House, the agreement focuses on building secure and diversified supply chains for minerals essential to high-tech manufacturing — from electric vehicles and semiconductors to defense systems. The pact follows similar US agreements with Malaysia and Thailand, all part of Washington’s push to counter China’s dominance in the global rare earth market.
China currently controls nearly 70% of mining and 90% of refining of rare earth elements, which are vital to modern technologies. Recent Chinese export restrictions on materials containing rare earth components have raised global concerns about supply security.
Geopolitical Context
The timing of the deal is significant — it comes just days before Trump’s planned meeting with Chinese President Xi Jinping in South Korea. Analysts say the Tokyo agreement sends a clear signal that Washington is working closely with allies to safeguard strategic resources and limit Beijing’s leverage over global supply chains.
“Even if alternative production takes years to develop, building these partnerships changes the balance of power,” said Charles Chang of Fudan University.
Experts, however, caution that reducing global dependence on China will take time. According to John Mavrogenes, a professor at the Australian National University, “China is still far ahead in refining capabilities. Establishing new supply chains could take a decade.”
Symbolism and Diplomacy
Beyond trade and strategy, the Tokyo ceremony also highlighted strong cultural ties. Prime Minister Takaichi presented Trump with 250 cherry trees to mark America’s upcoming 250th anniversary, symbolizing friendship between the two nations.
The agreement represents a growing alignment between the US and Japan as they navigate shifting power dynamics in Asia, with rare earth security emerging as a central pillar of their economic cooperation.
