Environmental Toll of U.S.-China Trade Truce: Rare Earth Mining Surges

London, June 11, 2025— The U.S.-China framework agreement announced on Tuesday to lift China’s export curbs on rare earth minerals has sparked optimism for global supply chains but raised alarm among environmentalists, as intensified mining to meet U.S. demand threatens ecosystems and undermines sustainability efforts. The deal, reached after two days of talks in London, aims to stabilize a faltering trade truce, but its environmental consequences could ripple across China’s mining regions and beyond.

Ecological Strain from Rare Earth Mining

China has decided to relax rules on seven important rare earth elements—samarium, gadolinium, terbium, dysprosium, lutetium, scandium, and yttrium—after months of supply issues that stopped exports to the U.S., which is a major market for magnets used in electric vehicles, wind turbines, and defense systems.

To meet renewed demand, China is ramping up production at mining hubs like Bayan Obo in Inner Mongolia, which supplies 60% of global rare earths. However, the environmental cost is steep: rare earth mining generates toxic sludge, radioactive waste, and heavy metal contamination, with a single ton of rare earths producing up to 2,000 tons of waste, according to a 2024 report by the Chinese Academy of Sciences.

In Bayan Obo, decades of mining have left vast tailings ponds laced with thorium and other pollutants, contaminating groundwater and rendering nearby farmland unusable. “The trade truce means more mining, which means more environmental devastation,” said Liu Wei, an environmental scientist at Peking University. Local communities report rising health issues, including respiratory problems and cancer, linked to mining runoff.

The agreement, which U.S. Commerce Secretary Howard Lutnick called a “fundamental” step to stabilize trade, lacks provisions to address these environmental impacts, prompting criticism from groups like Greenpeace East Asia, which called for stricter oversight on June 10, 2025.

China’s Ministry of Ecology and Environment has pledged to enforce tighter regulations, but enforcement remains inconsistent. In 2024, only 30% of rare earth mines met national environmental standards, per government audits. The push to supply the U.S., which consumed 12% of global rare earths in 2024, could exacerbate these issues, as Beijing prioritizes economic output over ecological safeguards. “This deal solves a trade problem but creates a bigger environmental one,” said Sarah Chen, an analyst at the Wilson Center’s China Environment Forum.

Global Sustainability Challenges and Alternatives

The environmental fallout from increased rare earth production clashes with global sustainability goals, including the Paris Agreement’s 2030 targets, which rely heavily on clean energy technologies powered by these minerals. Electric vehicle motors and wind turbines, key to reducing carbon emissions, depend on rare earth magnets, but the mining process emits significant greenhouse gases and destroys ecosystems. A 2025 study by the International Energy Agency estimates that rare earth mining contributes 1.5% of global industrial emissions, a figure likely to rise as production scales up.

The trade truce has also reignited calls for sustainable alternatives. In the U.S., the Department of Energy allocated $500 million in April 2025 to research magnet recycling and synthetic substitutes, but these technologies remain years from commercial viability. Australia and Canada are expanding their rare earth mining, with projects like Lynas Corporation’s Mount Weld mine aiming to reduce reliance on China by 2027. However, these operations face similar environmental challenges, and their output—projected at 10% of global supply—cannot yet match China’s scale.

European leaders, including European Central Bank President Christine Lagarde, who visited Beijing on June 11, 2025, urged both nations to integrate environmental safeguards into trade agreements. “Economic stability cannot come at the expense of our planet,” Lagarde said, advocating for global cooperation to develop cleaner mining technologies. Meanwhile, consumer groups in the U.S. and Europe are pressuring automakers like Tesla and Volkswagen to disclose their rare earth sourcing practices, with some launching boycotts over environmental concerns.

Rare earth mining in China’s Bayan Obo region has created a toxic lake spanning 11 square kilometers, containing enough radioactive waste to fill 20 Olympic-sized swimming pools, according to a 2023 environmental survey by the Chinese Academy of Sciences.

Health Risks for Mining Communities

Communities near China's mining sites, where exposure to toxic byproducts is a growing concern, are suffering due to the surge in rare earth mining. In Ganzhou, Jiangxi Province, another major rare earth hub, residents have reported a 20% increase in hospital admissions for respiratory and skin conditions since mining intensified in early 2025, according to local health authorities. The use of ammonium sulfate and other chemicals in ore processing has polluted rivers, affecting drinking water supplies for over 100,000 people in the region.

Health experts warn that the long-term impacts could be severe. “Rare earth mining releases heavy metals like cadmium and lead, which accumulate in the body over time,” said Dr. Zhang Mei, a public health researcher at Fudan University. “Children and pregnant women are particularly vulnerable.” Despite these risks, the trade agreement does not address worker safety or community protections, drawing criticism from international labor and environmental organizations. On June 10, 2025, the United Nations Environment Programme called for an independent assessment of China’s rare earth mining practices, a request Beijing has yet to acknowledge.

China has invested $1.2 billion since 2023 in mine remediation projects, such as reforestation and wastewater treatment, but progress is slow. Only 15% of contaminated sites in Bayan Obo have been partially restored, per a 2024 government report. The pressure to meet U.S. demand may further delay these efforts, as state-owned mining companies prioritize production quotas over environmental cleanup.

Push for International Accountability

The environmental and health impacts of the trade truce have spurred demands for international accountability. Environmental NGOs and global watchdogs are urging the U.S. and China to include binding ecological commitments in the comprehensive trade agreement due by August 10, 2025. The World Trade Organization, which facilitated the Geneva truce, is exploring a framework for “green trade” standards that could impose penalties for environmentally harmful practices, though negotiations remain in early stages.

In the U.S., lawmakers are pressing the Trump administration to tie rare earth imports to environmental benchmarks. On June 11, 2025, Senator Maria Cantwell introduced a bill requiring U.S. companies to certify that imported rare earths meet minimum environmental and labor standards, though it faces opposition from industry groups citing cost concerns. “We can’t fuel our clean energy future with dirty mining,” Cantwell said in a statement. Meanwhile, China’s Vice Commerce Minister Li Chenggang defended Beijing’s environmental record, claiming on June 10 that “significant progress” has been made in sustainable mining practices.

The debate underscores the tension between economic imperatives and environmental responsibility. Without enforceable measures, the trade truce risks amplifying the ecological damage of rare earth mining, potentially undermining the very clean energy goals it seeks to support. “This is a critical moment to align trade with sustainability,” said Dr. Anika Patel of Oxford University. “The world is watching.”
