The global race to secure critical minerals supply chains is increasingly fought not only in mines but in processing plants. While Australia is one of the world’s largest producers of rare earth elements (REEs), most of the world’s refining capacity remains concentrated in China, which processes most of the global rare earth output.
Over the past decade, governments across advanced economies have begun looking for ways to diversify the midstream segment of the supply chain. These are the complex stages of processing and separation that transform mined ore into materials used in electric vehicles, wind turbines, electronics, and defence systems.
Australia’s Lynas Rare Earths has become one of the few significant non-Chinese players in this space. Yet a critical part of Lynas’s supply chain sits outside Australia; its processing facility, for example, is in Malaysia.
The Lynas Advanced Materials Plant (LAMP), located in Kuantan in Malaysia’s Pahang state, has operated since 2012 and remains the largest rare-earth separation facility outside China. The plant processes concentrate from Lynas’s Mount Weld mine in Western Australia, producing separated rare earth oxides used in global manufacturing.
The decision to locate the facility in Malaysia reflects a combination of economic, regulatory and geopolitical considerations. It also illustrates how partnerships across borders are becoming central to building resilient critical minerals supply chains.
For Canada, which is seeking to strengthen its own critical minerals strategy while deepening engagement with Indo-Pacific partners, the Lynas case offers several useful insights.
Why Malaysia?
At first glance, processing Australian rare earths in Malaysia may appear counterintuitive. Australia is politically stable, resource-rich. and closely aligned with Western allies. Yet several factors made Malaysia an attractive location for Lynas’s processing facility.
Industrial economics played an important role. Rare earth processing is energy- and chemical-intensive. Malaysia offered lower construction and operating costs compared with Australia, as well as access to existing industrial infrastructure and port facilities. The Kuantan site is located within a broader industrial corridor, allowing Lynas to operate within an established manufacturing ecosystem. Malaysia’s broader electronics, petrochemical, and advanced materials sectors also provided the skilled labour, chemical processing expertise, and logistics infrastructure necessary for large-scale separation. Few Southeast Asian countries combine these capabilities with comparable regulatory capacity.
Regulatory conditions also mattered. Rare earth processing produces residues containing naturally occurring radioactive materials, including thorium. Managing these residues requires specialized regulatory frameworks and long-term storage arrangements, which can complicate project approvals in many jurisdictions. Malaysia provided a regulatory pathway that made the project feasible at the time the facility was proposed. Crucially, Malaysia already possessed a regulatory framework for facilities handling naturally occurring radioactive materials, allowing the project to move through an established licensing pathway rather than facing the regulatory uncertainty that has delayed similar projects elsewhere.
Geography and market access were also important. Malaysia’s position in Southeast Asia places it close to major downstream manufacturing hubs in China, Japan, and South Korea. Locating processing capacity in the region helped Lynas integrate into established Asian industrial supply chains.
These factors highlight an important point. Developing processing capacity is not simply a matter of geology. It depends on broader industrial ecosystems that include infrastructure, technical expertise, regulatory frameworks and proximity to manufacturing markets. In Southeast Asia, Malaysia’s hosting of the Lynas separation plant remains one of the few examples of value-added rare earth processing capacity operating outside China within the region.
The strategic bottleneck in rare earth supply chains
Rare earth supply chains differ from many other mineral commodities because the most strategically sensitive stage is not mining but processing. Separating rare earth elements from ore requires complex chemical processes, specialized equipment and tightly managed waste streams. Yet the value chain extends well beyond separation: rare earth oxides must still be converted into metals, alloys and ultimately permanent magnets used in advanced technologies. As a result, value creation and strategic leverage are distributed across a long and geographically fragmented industrial chain. These facilities are capital-intensive and technically demanding to operate.
China’s dominance in rare earth supply chains emerged not only from its resource base but from decades of investment in separation and refining capacity. By the early 2000s, many processing facilities in Australia, Europe, and the U.S. had closed due to environmental costs and competition from lower-cost Chinese production.
As a result, even when rare earths are mined outside China, they are often still sent to Chinese facilities for processing. This midstream dependence has become one of the central vulnerabilities that the U.S. and other Western governments are now addressing.
In this context, Lynas occupies a unique position as one of the very few companies capable of producing separated rare earth oxides outside China. Since beginning operations in 2012, the facility has supplied rare earth oxides to Japanese and other international manufacturers and demonstrated that large-scale separation outside China is commercially viable.
The challenges of hosting rare earth processing
The Lynas facility has also highlighted the political and social complexities associated with rare earth processing.
Since its establishment, the plant has faced periodic public scrutiny and political debate in Malaysia. Civil society organizations and opposition politicians have raised concerns about environmental risks and the management of radioactive residues. These concerns became a recurring issue in Malaysian domestic politics and led to several regulatory reviews of the plant’s operating licence.
At various points, Malaysian authorities imposed additional licence conditions on Lynas, including requirements related to waste management. Regulatory conditions attached to Lynas’s 2023 operating licence required the company to relocate certain early-stage processing activities, specifically cracking and leaching, outside Malaysia. Lynas has commissioned these stages at its Kalgoorlie facility in Western Australia, which opened in late 2024, though initial ramp‑up involved some commissioning disruptions.
In March 2026, Malaysia renewed Lynas Malaysia’s operating licence for 10 years but imposed stricter conditions, including a formal review after five years. From that point, Lynas must ensure the Gebeng plant no longer produces radioactive waste and must treat existing water leach purification residues so they are no longer radioactive, while no new permanent disposal facilities will be approved.
The Malaysian experience illustrates that critical minerals projects must maintain strong environmental governance and credible regulatory oversight to sustain public trust.
In some cases, debates around the Lynas facility have also intersected with broader geopolitical competition in rare earth supply chains. Investigations into online campaigns surrounding the project have suggested that foreign influence networks amplified narratives about radiation and toxic waste despite repeated regulatory findings that the plant operates within safety limits. This highlights how strategic materials infrastructure can become a target not only of regulatory scrutiny but also of information competition.
A prototype for diversified supply chains
Despite these challenges, the Lynas–Malaysia partnership has become a key component of efforts by allied economies to diversify rare earth supply chains.
Japan played an important role in Lynas’s early development. Following China’s rare earth export restrictions in 2010, Japanese government agencies provided financial support to Lynas to help secure alternative supply sources for Japanese manufacturers.
More recently, the U.S. has invested in expanding rare earth processing capacity outside China, including projects involving Lynas in Australia and the U.S. supported by the U.S. Department of Defense.
These initiatives reflect a broader shift in critical minerals policy. Rather than attempting to replicate every stage domestically, many governments are now pursuing “distributed” supply chains in which different trusted partners host different stages of the rare earth value chain. However, downstream stages, particularly metal production, alloying and magnet manufacturing, remain heavily concentrated in China, meaning that true diversification requires investment across the entire value chain.
Malaysia’s role in the Lynas supply chain demonstrates how Southeast Asian countries can become important partners in these networks, even when they are not major producers of the underlying minerals.
Southeast Asia’s growing role in critical minerals supply chains
Malaysia’s involvement in the Lynas supply chain also reflects a broader trend in the regional critical minerals landscape. Southeast Asian countries are increasingly becoming important actors in global mineral value chains, not only as producers but also as processing and manufacturing hubs.
Indonesia has rapidly expanded nickel processing and battery materials production. Vietnam possesses significant rare earth resources and has begun exploring opportunities to develop downstream processing. Malaysia and Thailand host established electronics and manufacturing industries that rely on stable access to critical materials.
For countries such as Australia and Canada, engagement with Southeast Asia therefore has both economic and strategic dimensions. Partnerships in the region can help diversify supply chains while strengthening economic links with fast-growing Indo-Pacific markets.
Such engagement requires recognizing that many Southeast Asian countries seek not only to supply raw materials but to capture greater value through processing and manufacturing. Partnerships centred on technology co-operation, investment in midstream processing and environmental management, and longer-term industrial collaboration are therefore likely to resonate more strongly than approaches focused solely on supply security.
Canada, still developing its Indo-Pacific industrial relationships, can view the Lynas model as a practical template for how resource partnerships with Southeast Asian nations may emerge indirectly, through allied intermediaries and complementary investment rather than direct bilateral presence.
What Canada can learn
Canada’s critical minerals strategy has focused heavily on expanding domestic mining and processing capacity. While Canada’s resource base provides a strong foundation, the Lynas experience highlights several broader lessons.
First, processing capacity depends on industrial ecosystems. Rare earth refining is a specialized chemical industry that requires infrastructure, technical expertise and supportive regulatory frameworks. Building these ecosystems takes time and often requires partnerships that extend beyond national borders.
Second, resilient supply chains are inherently international. Mines, processing facilities, manufacturing hubs, and end markets are often located in different countries. Strengthening critical minerals security, therefore, requires co-ordination among trusted partners.
Recent efforts by Australia and Canada to deepen co-operation in critical minerals illustrate this point. Both countries share similar resource endowments, strong regulatory institutions, and close economic and security ties with the U.S. and other Indo-Pacific partners. On November 1, 2025, Australia and Canada signed a Joint Declaration of Intent on Critical Minerals Collaboration in Toronto, setting out a common framework for investment co-ordination, standards, and policy approaches. Discussions have also begun on how initiatives such as Australia’s Critical Minerals Strategic Reserve and Canada’s Critical Minerals Sovereign Fund might complement each other as both countries seek to strengthen supply resilience.
Practical co-operation is also emerging in areas such as geological mapping, technical knowledge sharing on extraction and processing, and initiatives to address workforce shortages across the mining sector. A pilot exchange program involving industry, academic institutions, and government partners in both countries is being developed to help build the specialized skills needed to expand critical minerals production.
Closer co-ordination could allow Australia and Canada to align investment priorities, support complementary projects across the supply chain and engage more effectively with Indo-Pacific partners. For example, Canadian investment and financial expertise could support projects involving Australian mineral production, while Australian experience in developing rare earth supply chains could inform Canada’s own efforts to expand midstream processing.
In this way, co-operation between the two countries could amplify broader allied efforts to diversify supply chains and reduce vulnerabilities in strategically important materials.
Finally, maintaining public trust will remain essential as critical minerals development expands. Strong environmental governance, responsible waste management, and transparent regulatory oversight are critical for sustaining confidence in mining and, increasingly, processing projects. As Australia and Canada deepen co-operation with partners across the Indo-Pacific, credible regulatory systems and responsible engagement with local communities, including Indigenous Peoples,, will help underpin the trusted partnerships needed to build resilient and diversified supply chains.
A strategic partnership model
The Lynas facility in Malaysia illustrates how critical minerals supply chains are evolving.
Rather than relying solely on domestic production, countries are increasingly building networks of complementary capabilities, linking resource producers, processing facilities, and manufacturing centres across multiple regions.
Australia’s partnership with Malaysia reflects a pragmatic recognition that supply chain resilience often depends on regional co-operation and distributed industrial capacity.
For Canada, which is seeking to strengthen its critical minerals strategy while expanding its engagement in the Indo-Pacific, the Lynas case provides a useful example of how such partnerships can develop in practice.
If managed carefully, collaborations of this kind can transform geological resources into enduring strategic relationships, helping to build a more diversified and resilient global critical minerals system.
