China's Strategic Export Controls: Navigating the Landscape of Battery Technology and Rare Earths
China is increasingly leveraging export controls as a powerful instrument of statecraft, specifically targeting critical materials and technologies essential for advanced industrial and clean energy sectors.
China is increasingly leveraging export controls as a powerful instrument of statecraft, specifically targeting critical materials and technologies essential for advanced industrial and clean energy sectors. This brief provides a detailed analysis of two key measures: the export restrictions on heavy rare earths and on advanced battery technologies.
The rare earth controls, announced on April 4, 2025, took immediate effect and were a direct response to escalating U.S. tariffs, signifying a reactive, retaliatory move within the broader U.S.-China trade war. In contrast, the battery technology restrictions, enacted on July 15, 2025, followed a public consultation period, indicating a more deliberate and long-planned industrial policy to secure technological dominance in the clean energy transition.
Both sets of controls are rooted in a newly formalized legal framework—the 2020 Export Control Law and 2024 Regulations on Dual-use Items—that provides a systematic basis for such actions. The strategic shift from controlling traditional "dual-use" military-civilian technologies to prioritizing purely industrial technologies highlights China's intent to weaponize its market position to impede foreign competitors and solidify its leadership in emerging economic sectors.
These measures will have profound and lasting impacts on global supply chains, necessitating urgent reassessment of sourcing strategies and accelerated diversification efforts for any company reliant on these critical materials and technologies.
Section 1: Key Policy Announcements
China's recent export controls were formalized through two distinct announcements, each with a different strategic context.
Rare Earth Export Controls (April 4, 2025)
| Material | Key Applications | Control Status |
|---|---|---|
| Samarium | Permanent magnets, nuclear reactors | Restricted |
| Gadolinium | MRI contrast agents, nuclear applications | Restricted |
| Terbium | Phosphors, magnets, fuel cells | Restricted |
| Dysprosium | High-performance magnets, lasers | Restricted |
| Lutetium | Medical imaging, catalysts | Restricted |
| Scandium | Aerospace alloys, fuel cells | Restricted |
| Yttrium | LEDs, superconductors, lasers | Restricted |
These materials are crucial for defense, energy, and automotive applications. The controls represent a direct response to escalating U.S. tariffs and restrictions on high-end semiconductors.
Battery Technology Export Controls (July 15, 2025)
| Technology | Key Applications | Control Status |
|---|---|---|
| LFP Cathode Preparation | Electric vehicle batteries | Restricted |
| LMFP Cathode Preparation | Next-gen EV batteries | Restricted |
| Lithium Carbonate/Hydroxide from Spodumene | Battery-grade lithium production | Restricted |
| Direct Lithium Extraction (DLE) | Brine lithium processing | Restricted |
| Gallium Metal Extraction | Semiconductors, LEDs | Restricted |
This is a control on process technologies, not materials, covering preparation technologies for Lithium Iron Phosphate (LFP) and Lithium Manganese Iron Phosphate (LMFP) battery cathode materials, various lithium processing technologies, and gallium metal extraction technologies.
Section 2: Strategic Rationale and Geopolitical Context
These controls are not isolated events but are deeply embedded within China's evolving legal and strategic framework.
China's policy has shifted from ad-hoc, informal measures to a systematic approach underpinned by:
- • Export Control Law (ECL) of 2020
- • Regulations on Export Control of Dual-use Items (effective December 1, 2024)
This legal formalization provides a long-term basis for China's export policies but also introduces inflexibility, making them harder to reverse.
The rare earth controls were explicitly framed as a direct response to:
- • Increased U.S. tariffs
- • Restrictions on high-end semiconductors
- • Additions to China's "Unreliable Entity List"
The synchronous announcements on April 4, 2025, underscore the retaliatory and coordinated nature of this economic warfare.
China's strategy has evolved from restricting items with both civilian and military applications (the traditional "dual-use" focus) to specifically targeting technologies vital solely for the energy transition. This is a profound shift, demonstrating China's intent to use export controls to maintain its industrial lead in a key economic domain rather than just for traditional security purposes.
The 2025 rare earth restrictions build upon a clear historical pattern, most notably the 2010 restrictions on rare earth exports to Japan. That incident served as an early warning of China's willingness to use its market dominance as a geopolitical tool.
Section 3: Implications and Outlook
China's export controls have significant implications for global industry and supply chain security.
Short-Term Disruptions and Cost Increases
The immediate implementation of the rare earth controls has already led to significant disruptions:
- • Production suspensions in some manufacturing sectors
- • Companies like MP Materials forced to halt exports to China
- • Increased compliance costs for technology transfer agreements
- • Significant uncertainty for joint ventures and partnerships
These actions are designed to increase costs for foreign competitors and hinder their ability to compete effectively in both civilian and military markets.
The Paradox of Export Controls
While China enjoys considerable short-term leverage due to its near-monopolistic position (controlling over 90% of global rare earth refining and 99% of LFP cathode production), its aggressive use of this leverage carries long-term risks.
The more China restricts exports, the more urgent and well-funded global efforts to diversify supply chains and invest in domestic production become. This could ultimately undermine the very leverage China is seeking to preserve.
- • 90%+ of global rare earth refining
- • 99% of LFP cathode production
- • 65% of lithium refining capacity
- • 60% of battery cell production
- • Accelerated global diversification efforts
- • Increased investment in alternative technologies
- • Development of competing supply chains
- • Erosion of market dominance over time
Shifting Supply Chain Architecture
The restrictions on LFP and DLE technologies are a strategic attempt to lock in China's technological advantage. By controlling the knowledge and processes rather than just the physical resources, China is making it much harder for other nations to build independent battery supply chains from scratch.
This forces foreign companies and governments to either rely on Chinese imports or embark on costly and time-consuming efforts to develop their own advanced technologies.
We anticipate a continued, and potentially expanding, use of export controls by China. The U.S. and its allies are compelled to accelerate initiatives to build resilient, post-China supply chains through diversification, domestic investment, and international cooperation.
The long-term success of China's strategy will depend on the pace and efficacy of these global efforts, which face significant challenges given China's entrenched dominance and the difficulty of the industries involved.
