TL;DR
Sumitomo Metal Mining is seeking to develop rare-earth resources in the Philippines, while Sojitz is working on mines in Vietnam and Malaysia. This effort aims to create a China-independent supply chain for critical minerals. The initiative reflects Japan’s strategic move to diversify sources amid geopolitical tensions.
Japanese firms Sumitomo Metal Mining and Sojitz are actively developing rare-earth resources in Southeast Asia, aiming to establish a supply chain independent of China. This move is part of Japan’s broader strategy to diversify critical mineral sources amid geopolitical and supply chain concerns.
Sumitomo Metal Mining is seeking to tap into rare-earth mineral deposits in the Philippines to increase its production capacity. Meanwhile, trading house Sojitz is working on developing mines in Vietnam and Malaysia, targeting the growing demand for these critical materials. These initiatives are seen as efforts to create a more resilient and diversified supply chain for rare earths, which are vital for electronics, renewable energy, and defense industries.
Both companies’ actions are part of Japan’s strategic push to reduce dependence on China, which currently dominates global rare-earth production and processing. While specific project details are still emerging, these developments signal a significant shift in regional resource development efforts. The Philippine project is in initial exploration phases, and the Vietnamese and Malaysian mines are under development with expected operational timelines still being finalized.
Why It Matters
This development matters because rare earths are essential for modern technology and green energy solutions, and Japan’s move to diversify sources could impact global supply chains. Reducing reliance on China could also influence geopolitical dynamics, as countries seek to secure critical mineral supplies amid ongoing trade tensions and strategic competition.

Background
Japan has been increasingly concerned about supply chain vulnerabilities for rare earths, which are overwhelmingly produced and processed in China. Prior efforts have included stockpiling and investing in mining projects abroad. Southeast Asia, with its rich mineral deposits and proximity to Japan, is emerging as a strategic focus for resource development. The Philippines, Vietnam, and Malaysia are seen as promising locations for new mining projects, aligning with regional efforts to develop alternative supply sources.
“These developments reflect Japan’s strategic shift toward diversifying its critical mineral supply chain away from China, which has historically dominated the market.”
— An industry analyst
“We are committed to exploring sustainable and responsible rare-earth resource development in Southeast Asia to support global supply stability.”
