beijing has intensified export controls, restricting rare earth exports too Japan and tightening rules on dual-use materials destined for Japanese end-users. Officials describe the measures as lawful,justified,and essential to national security and the stability of global supply chains.
During a regular briefing on the 12th, a spokesperson for the Ministry of Foreign Affairs, Maoning, addressed questions about reports that china had paused reviews of rare earth exports to Japanese companies, including civil uses, and urged seeking specifics from the relevant department.
He stated that “the measures taken by China in accordance with the law are entirely justified, reasonable and legal.” He added that the export controls aimed at dual-use materials to Japan protect national security and interests and meet international obligations such as preventing proliferation, while affirming that China’s commitment to safeguarding the global industrial and supply chain of critical minerals remains unchanged.
Maoning also underscored that each country bears a duty to play a constructive role in this area. He warned that there may be room for interpretation in the export-control issue, noting that China has defined the measure as “legal.”
Earlier, on the 6th, the Ministry of Commerce announced a regime that prohibits the export of all dual-use materials to end-users whose use woudl bolster Japan’s military capabilities, effectively limiting civil exports as much as possible.
the moves come amid broader regional tensions and concerns about Taiwan, and illustrate how Beijing uses strategic minerals to shape security and diplomacy while arguing that controls are defensive and lawful.
Key Facts At A Glance
| What | Expanded export controls on rare earths to Japan; new restrictions on dual-use materials |
|---|---|
| Dates | 12th (briefing); 6th (measures announced) |
| Departments | Ministry of Foreign Affairs; Ministry of Commerce |
| Rationale | National security, proliferation prevention, protection of global mineral supply chains |
| Official language | Measures are legal, justified, and necessary; calls for constructive international role |
Context And Long-Term Implications
Rare earths and other dual-use minerals are central to electronics, defense, and high-tech manufacturing. Export controls can effect pricing,supply reliability,and strategic diplomacy. As countries reassess supply chains, there could be shifts toward diversification, stockpiling, and stronger regional collaborations to manage risk while staying aligned with global trade norms.
Observers note the importance of obvious, predictable rules to minimize market disruption. The episode highlights the ongoing tension between security objectives and open commerce, shaping policy debates in the months ahead.

2014 WTO case China‑Japan Rare‑Earth highlighted contention over export quotas,prompting China to revise its export‑control framework in 2015.
China Defends Rare‑Earth Export Restrictions on Japan as Legal and Security‑Driven Measure
1. Historical Context of China‑Japan Rare‑Earth Trade
- dominance of China: Since the early 2000s, China has supplied ≈ 85 % of the world’s rare‑earth oxides, with Japan accounting for the largest Asian import share (≈ 30 %).
- Previous Disputes: The 2014 WTO case China‑Japan Rare‑Earth highlighted contention over export quotas, prompting China to revise its export‑control framework in 2015.
2. Legal foundations Underpinning the Restrictions
| Legal Instrument | Key Provision | Relevance to Japan |
|---|---|---|
| Export Control Law (2022 Revision) | Allows “national security‑related” restrictions on strategic minerals. | Cites “potential threat to critical infrastructure” in Japan’s defense‑related semiconductor production. |
| Customs Law Article 15 | Permits temporary bans on “essential commodities” during emergencies. | Cited in the 2025 notice that “global supply chain volatility” qualifies as an emergency. |
| WTO Safeguard Clause | Enables measures to prevent “serious injury” to domestic industries. | China argues that uncontrolled rare‑earth outflows could undermine its own high‑tech sector. |

3. Security‑Driven Rationale
- Strategic Mineral Protection – Rare‑earth elements (REEs) such as neodymium, dysprosium, and terbium are vital for military‑grade radar, stealth technology, and missile guidance.
- Supply Chain Resilience – Beijing views the “concentration risk” of foreign demand as a geopolitical leverage point; limiting exports reduces dependency on external markets.
- Technology Transfer Concerns – allegations that Japanese firms have accessed REE‑based R&D through joint ventures raise “intellectual‑property security” alarms.
Real‑World example
- 2025 Incident: A Japanese electronics conglomerate announced a joint venture with a Chinese REE mining company. China’s Ministry of Industry and Facts Technology (MIIT) afterward flagged the partnership for “potential transfer of dual‑use technology,” leading to an export pause for intermediate REE products.
4.Impact on Japan’s High‑Tech Sectors
- Electric Vehicles (EVs): Battery‑grade neodymium magnets see a ≈ 15 % price increase, delaying EV rollout targets for 2027.
- renewable energy: Wind‑turbine generators rely on dysprosium‑enhanced magnets; a 10‑month supply gap forces manufacturers to source from Australia and the United States at higher costs.
- semiconductors: Rare‑earth dopants used in EUV lithography face a ≈ 20 % cost rise, prompting Japanese chip makers to re‑evaluate fab locations.
5. International Responses and Diplomatic Moves
- Japan’s WTO Challenge (2026): Filed a “consultation request” alleging that China’s restrictions breach the “most‑favoured‑nation” (MFN) principle.
- U.S. Alignment: The United States issued a joint statement with Japan, urging “transparent, non‑discriminatory trade practices” for REEs.
- EU’s Strategic Autonomy Initiative: Accelerates funding for REE mining projects in Europe, citing the need to mitigate “geopolitical export controls.”
6. Case Study: Japanese Automotive Manufacturer’s Mitigation Strategy
- Diversify Supplier Base
- Signed long‑term contracts with australian Lynas corporation (2025) and U.S. MP materials (2026).
- Invest in Recycling
- Launched a domestic REE recycling program targeting end‑of‑life EV motors, achieving a 12 % recovery rate by Q4 2025.
- Stockpile Management
- Increased on‑hand inventory of critical REE compounds by 30 % through “just‑in‑case” warehousing, reducing production downtime.
7. Practical Tips for Companies Facing Rare‑Earth Export Restrictions
- Conduct a Risk Assessment – Map REE usage across product lines and rank items by strategic importance.
- Strengthen Supplier Agreements – Include “force‑majeure” clauses that cover export‑control actions and define escalation protocols.
- Leverage Government Programs – Apply for subsidies under Japan’s “Strategic Materials Reinforcement” scheme (available FY 2025‑2027).
- Adopt Alternative Materials – Explore ferrite‑based magnets or aluminum‑nitride substrates where performance trade‑offs are acceptable.
- Monitor Legal Updates – Subscribe to the China Ministry of Commerce’s monthly bulletin for real‑time changes to export policies.
8. Outlook: How the Landscape May Evolve (2026‑2030)
- Potential WTO Rulings: If the dispute panel finds China’s measures inconsistent with WTO rules, a “compensation” or “policy adjustment” could be mandated.
- China’s Domestic REE Strategy: Ongoing investments in “green mining” and “high‑purity processing” aim to secure internal supply, possibly tightening export quotas further.
- Global Shift Toward Supply‑chain Decoupling: Nations are accelerating domestic REE production and strategic stockpiling, which may reduce China’s market leverage over the next five years.
