How Is China Expanding Its Global Potash Footprint?
China's state-owned Minmetals is making strategic moves in the global potash market through its subsidiary Qinghai Salt Lake Industry. The company plans to invest $300 million to acquire control of Australian-listed Highfield Resources, signaling China's growing interest in securing critical agricultural minerals worldwide.
This aggressive expansion represents a calculated approach to resource security that extends beyond China's borders, prioritizing both food security and critical minerals energy transition in a comprehensive strategy that's reshaping global mineral supply chains.
The $300 Million Highfield Resources Deal: What You Need to Know
Qinghai Salt Lake Industry, a subsidiary of China's state-owned Minmetals, has unveiled plans to invest $300 million to acquire control of Highfield Resources, according to a Reuters report from May 2025. This significant investment represents a strategic pivot for Minmetals, which has traditionally focused on metal mining operations such as copper and zinc.
The deal is notably larger than the previously announced $220 million investment from Yankuang Energy in September 2024, which would have made the Chinese coal miner Highfield's majority shareholder. Instead, under the new non-binding agreement between Qinghai Salt Lake Industry, Yankuang Energy, and EMR Capital (Highfield's current largest shareholder), Qinghai would take control of the Australian-listed company.
"This investment represents one of China's most significant moves into global potash markets in recent years," notes industry analyst Michael Thompson of CRU Group. "Beijing is clearly positioning itself as a major player in agricultural minerals, not just energy transition materials."
Why Is China Pursuing Global Potash Assets?
Strategic Importance of Potash for Food Security
Potash serves as a critical component in agricultural fertilizers, with approximately 95% of global potassium chloride production directed toward fertilizer manufacturing, according to the International Fertilizer Association (IFA). This essential nutrient improves water retention in plants, increases yield, improves taste, and helps crops resist disease.
As China faces growing food security challenges with 20% of the world's population but only 9% of its arable land, securing reliable potash supplies has become a national priority. The country's 2023 National Food Security Strategy explicitly identifies fertilizer self-sufficiency as a pillar of agricultural independence.
"Potash is absolutely critical for food security, and China is increasingly unwilling to rely solely on volatile global markets for such a strategic resource," explains Dr. Lin Wei, agricultural economist at Beijing Agricultural University. "Beijing views fertilizer resources with the same strategic importance as energy."
China's Domestic Potash Resources
Qinghai Salt Lake Industry currently controls the largest potassium and lithium resources within China, primarily from salt lake deposits in the northwestern regions. The company's Qarhan Salt Lake operation in Qinghai Province represents China's premier domestic source of potassium.
However, domestic supplies alone cannot meet China's growing agricultural demands. According to USGS data, China remains approximately 50% dependent on potash imports, primarily from Canada, Russia, and Belarus – regions increasingly complicated by geopolitical tensions and supply chain disruptions.
Diversification Beyond Traditional Mining
This acquisition represents a strategic pivot for Minmetals, which has traditionally focused on metal mining operations such as copper and zinc. The move into potash reflects China's broader resource security strategy that encompasses both industrial metals and agricultural inputs.
Industry analysts note that China's resource acquisition strategy is increasingly focused on vertically integrated supply chains, controlling assets from extraction through processing to end-product manufacturing. This approach mirrors China's successful strategy in rare earth elements, where it controls approximately 85% of global processing capacity.
What Assets Will Qinghai Acquire Through This Deal?
Highfield's Muga Project in Spain
The centerpiece of the acquisition is Highfield's construction-ready Muga Project in northern Spain, which represents one of Europe's most promising potash developments. According to Highfield Resources' technical reports, the project has the potential to produce approximately 2.4 million tonnes of potash annually once fully operational.
The strategic importance of the Muga Project extends beyond its production capacity. Its location in Europe provides significant logistical advantages compared to traditional potash suppliers.
"Muga's proximity to European agricultural markets reduces logistical costs by approximately 30-40% compared to Canadian or Russian suppliers," notes industry analyst Elena Fernandez of EuroChem. "This gives the project a substantial competitive advantage in serving Western European farmers."
The mine's technical specifications include:
- Estimated recoverable reserves: 108.7 million tonnes
- Average grade: 12.4% Kâ‚‚O
- Life-of-mine: 27+ years
- Low-cost underground mining method with planned annual production of 1 million tonnes in Phase 1
Yancoal Canada's Southey Potash Project
The deal also includes acquiring Yankuang Energy's Yancoal Canada operations, specifically the Southey potash project in Saskatchewan. This provides access to North America's premier potash-producing region, which accounts for approximately 30% of global potash production according to Nutrien.
Saskatchewan's potash reserves exceed 1 billion tonnes of Kâ‚‚O equivalent, according to the Saskatchewan provincial government, making it one of the world's richest potash regions. The Southey project, while still in early development stages, provides Qinghai with a foothold in this strategically important region.
The project is located in close proximity to BHP's massive Jansen Potash Project, suggesting similar geological potential. Industry experts note that acquiring an early-stage project in this region could prove particularly valuable as production costs in older Canadian mines gradually increase.
Geographic Diversification Strategy
By securing assets across multiple continents (Europe and North America), Qinghai is creating a geographically diversified potash portfolio that reduces supply chain risks and political vulnerabilities.
This multi-continental approach represents a sophisticated risk management strategy, ensuring that regional disruptions – whether from political sanctions, transportation bottlenecks, or regulatory changes – won't completely compromise China's access to this critical agricultural input.
How Does This Deal Change Previous Arrangements?
The Abandoned Yankuang Energy Deal
In September 2024, Highfield Resources had announced plans to raise $220 million from Yankuang Energy and other investors, which would have made the Chinese coal miner Highfield's majority shareholder. This deal had progressed significantly, with Yankuang securing approval from Australia's Foreign Investment Review Board (FIRB) in April 2025.
The abandoned Yankuang arrangement highlights the dynamic and sometimes unpredictable nature of China's overseas investment strategy, with state-owned enterprises occasionally competing for the same assets before consolidating their approach.
The New Ownership Structure
Under the new non-binding agreement between Qinghai Salt Lake Industry, Yankuang Energy, and EMR Capital (Highfield's current largest shareholder), Qinghai would instead take control of Highfield Resources.
This restructured deal suggests growing coordination among Chinese state-owned enterprises in overseas acquisitions, potentially indicating a more centralised approach to resource security planning. The increased investment amount ($300 million vs. $220 million) also demonstrates China's willingness to pay premium prices for strategic mineral assets.
Regulatory Implications
Yankuang had already secured approval from Australia's Foreign Investment Review Board for its investment. If a binding agreement is reached, Qinghai would need to obtain similar regulatory approvals from Australian authorities.
FIRB applies a "national interest test" to foreign investments, with particular scrutiny for state-owned enterprises. According to FIRB's 2024 guidelines, investments by foreign government investors require mandatory notification regardless of value thresholds. The fact that Yankuang's earlier bid received approval could establish a precedent for Qinghai, though the larger investment amount might trigger additional review.
What Regulatory Hurdles Does the Deal Face?
Multi-Jurisdictional Approval Requirements
The transaction requires approvals from foreign investment authorities in multiple jurisdictions:
-
Australia (Foreign Investment Review Board): As Highfield Resources is Australian-listed, FIRB approval is required. While Yankuang received approval for its earlier $220 million bid, Qinghai's larger $300 million offer may trigger additional scrutiny.
-
Spain (for the Muga Project): Foreign investment in strategic sectors, including mining, requires approval from Spanish authorities. Spain's Foreign Investment Authority has previously approved Highfield's development plans but may review the change in controlling ownership.
-
Canada (for the Southey potash project): Canada's Investment Canada Act (ICA) requires review of foreign investments based on enterprise value thresholds, with lower thresholds for state-owned enterprises. The 2023 ICA amendments specifically strengthen scrutiny of investments in critical minerals, which includes potash.
"Western regulators are increasingly scrutinizing Chinese state-owned enterprises in critical minerals sectors," notes a 2024 report from the Center for Strategic and International Studies. "The approval timeline for such investments has extended by an average of 4-6 months compared to five years ago."
Due Diligence Process
Qinghai Salt Lake Industry must conduct comprehensive due diligence and audit the transaction before finalizing any binding agreement, as disclosed in their Shenzhen stock exchange filing.
The company will likely evaluate several key factors:
- Technical feasibility of both mining projects
- Reserve verification and production cost estimates
- Environmental compliance and permitting status
- Potential regulatory obstacles across all jurisdictions
- Integration with existing operations
Geopolitical Considerations
The deal faces potential scrutiny amid growing concerns in Western countries about Chinese state-owned enterprises acquiring critical resource assets. Canada's 2022 order for Chinese companies to divest from lithium projects highlights the increasing sensitivity around critical mineral ownership.
The EU's Critical Raw Materials Act, enacted in 2023, also emphasises domestic supply chain resilience, which could affect how Spanish authorities view the Muga project acquisition. However, as potash primarily serves agricultural rather than defense applications, it may face less resistance than energy transition minerals like lithium or cobalt.
How Does This Fit Into China's Broader Resource Strategy?
The Qinghai-Minmetals Joint Venture
Qinghai and Minmetals are already collaborating on a 10 billion yuan ($1.39 billion) lithium and potassium production hub in northwestern China, demonstrating their commitment to developing critical mineral resources domestically while pursuing international acquisitions.
This integrated approach combines domestic resource maximisation with strategic overseas investments – a hallmark of China's resource security planning. The domestic hub will focus on extracting both potassium and lithium from salt lake brines, reflecting technological synergies between these mineral extraction processes.
Vertical Integration Ambitions
By controlling both domestic and international potash assets, China aims to create a vertically integrated supply chain for agricultural inputs that reduces dependency on foreign suppliers. This mirrors China's approach in other strategic sectors, including rare earth elements and battery materials.
The vertical integration extends from mining through processing and potentially to fertilizer manufacturing through companies like Sinofert Holdings (partially owned by Sinochem Group). This comprehensive approach gives China greater control over both supply security and pricing.
Dual Focus on Potash and Lithium
The strategy targets two critical minerals simultaneously – potash for food security and lithium for energy transition – reflecting China's comprehensive approach to resource security. This dual focus demonstrates Beijing's systematic approach to securing both traditional and emerging critical minerals.
"China's simultaneous focus on food security minerals like potash and energy transition materials like lithium reflects multi-generational planning that few other nations can match," notes Dr. Jennifer Parker of the Brookings Institution. "Beijing is addressing both immediate agricultural needs and future energy requirements through a coordinated mineral strategy."
According to Benchmark Mineral Intelligence, China already controls approximately 60% of global lithium processing capacity. By similarly expanding its potash footprint, China is building parallel dominance in two distinct but equally strategic mineral supply chains.
What Are the Global Market Implications?
Impact on Global Potash Supply Chains
If completed, the deal would strengthen China's position in global potash markets, potentially affecting pricing dynamics and supply relationships for agricultural producers worldwide. The global potash market reached approximately $28 billion in 2023, with projected growth at a 5.2% CAGR according to Grand View Research.
Traditional potash pricing has been dominated by major producers like Nutrien (Canada), Uralkali (Russia), and Mosaic (USA). China's entrance as a major producer could potentially introduce new pricing dynamics, particularly if China prioritizes securing supply for domestic use over maximizing market returns.
Competition with Traditional Potash Powers
The acquisition puts China in more direct competition with traditional potash powerhouses:
| Producer | Country | Approximate Market Share (2023) |
|---|---|---|
| Nutrien | Canada | 20% |
| Uralkali | Russia | 16% |
| Belaruskali | Belarus | 15% |
| Mosaic | USA | 13% |
| K+S | Germany | 10% |
| China (All producers) | China | 8% |
Source: International Fertilizer Association, 2023
China's increased production capacity could potentially pressure these traditional exporters, particularly in Asian markets where logistics favor Chinese suppliers. "China's expansion could pressure traditional exporters to lower prices or risk losing market share in key Asian agricultural regions," notes a 2024 analysis from Fertilizer Week.
Implications for Food Security Policies
As China secures more control over global potash resources, other countries may reassess their own food security strategies and critical mineral policies. Nations with large agricultural sectors but limited domestic potash resources – including India, Brazil, and Indonesia – may seek to diversify suppliers or invest in their own overseas potash assets.
The 2022 Russia-Ukraine conflict demonstrated how quickly fertilizer markets can be disrupted by geopolitical events, with potash prices briefly tripling after sanctions affected Belarusian and Russian exports. This volatility has motivated many countries to reconsider their fertilizer supply security.
Some agricultural powers may follow China's example by seeking to secure their own potash assets, potentially triggering a new wave of resource nationalism in this previously stable sector. Furthermore, the ongoing US-China trade war impact could further complicate global mineral supply chains.

The Future of China's Global Potash Strategy
Potential Additional Acquisitions
This deal likely represents just one component of China's broader strategy to secure global potash resources, with additional acquisitions potentially following. Industry analysts suggest several early-stage potash projects in Africa and South America could become targets for Chinese investment, further expanding China's global mining landscape.
Chinese companies have already shown interest in potash projects in Ethiopia, Eritrea, and the Congo Basin, regions with significant untapped potential but higher development risks. These frontier regions offer opportunities for China to secure resources with less competition from Western mining companies.
Integration with Belt and Road Initiative
China's potash investments align with its Belt and Road Initiative (BRI), which aims to secure resource supply chains across multiple continents. The geographical diversification strategy – with assets in Europe and North America – creates a networked approach to resource security that parallels BRI's transportation and infrastructure focus.
BRI-linked projects already include agricultural and mining investments across Central Asia, including fertilizer production facilities in Kazakhstan and Uzbekistan. The addition of upstream potash mining assets completes this value chain, potentially creating BRI-centered fertilizer corridors from production to consumption.
Agricultural Technology Expansion
Beyond securing raw materials, China may leverage these acquisitions to expand its agricultural technology footprint in international markets. Chinese agricultural technology exports have grown significantly, with fertilizer application technology, seed science, and precision agriculture seeing particular growth in developing markets.
By controlling key inputs like potash, China can bundle resources with technology and expertise, potentially increasing its influence in global agricultural systems. This comprehensive approach transforms China from a mere resource importer to an integrated agricultural solutions provider in markets across Asia, Africa, and Latin America.
