How a year of China’s rare-earth controls is reshaping supply chains

China’s export controls on seven rare-earth elements, imposed in April 2025, have resulted in a decline in global exports of rare earths and related magnets over the past year, impacting supply chains worldwide.

Since Beijing implemented export restrictions on key rare-earth elements in April 2025, China’s exports of these materials and related permanent magnets have decreased significantly, according to data analyzed by Nikkei Asia. This has contributed to supply shortages in industries such as electronics, renewable energy, and defense manufacturing.

Global manufacturers are experiencing increased costs and supply uncertainties, prompting shifts in sourcing strategies and inventory management. The export controls are seen as a strategic move amid ongoing trade tensions with Washington, which has raised concerns about long-term supply security.

Why It Matters

This development matters because rare earths are critical for the production of advanced technologies, including electric vehicles, wind turbines, and military equipment. Disruptions threaten to slow innovation and increase costs for industries worldwide, highlighting the geopolitical risks embedded in global supply chains.

Background

China, which supplies about 60% of the world’s rare earths, announced the export controls in April 2025 amid escalating trade tensions with the United States. The controls targeted seven key elements used in permanent magnets and other high-tech applications, intensifying supply chain concerns. Prior to this, China had already been a dominant supplier, but the restrictions marked a significant escalation in trade policy.

“The export controls have effectively tightened China’s grip on the rare-earth market, forcing companies worldwide to seek alternative sources or face shortages.”

“China’s export policies are within the framework of international trade rules and aim to protect national interests.”

— Li Wei, Chinese Ministry of Commerce spokesperson

What Remains Unclear

It is still unclear whether China will relax or expand these export controls in the near future. The outcome of upcoming US-China summit talks could influence future policy directions, but no definitive decisions have been announced.

What’s Next

Attention is focused on the upcoming US-China summit, scheduled for mid-2026, where discussions on trade and supply chain security are expected to take place. Meanwhile, companies continue to adapt by diversifying sources and increasing stockpiles.

Key Questions

How much have China’s rare-earth exports declined since the controls were introduced?

According to recent data, China’s exports of the targeted rare-earth elements and magnets have decreased by approximately 20-25% over the past year.

Which industries are most affected by these export restrictions?

Electronics, renewable energy (particularly wind turbines), and defense manufacturing are experiencing notable supply disruptions due to reduced availability of rare earths.

Are alternative sources of rare earths being developed?

Yes, some countries and companies are investing in domestic mining and recycling efforts, but these are not yet sufficient to fully offset China’s dominance.

What are the potential long-term impacts if the controls remain in place?

Prolonged restrictions could lead to sustained supply shortages, increased costs for high-tech manufacturing, and shifts in global supply chain strategies.
