The Missing Critical Minerals Investment

Foreign Affairs | Tom Moerenhout, Kevin Brunelli

China’s control over critical mineral supply chains expands through targeted capital injections at the pre-production stage, exploiting a structural financing gap in Western development pipelines. Western junior exploration firms fund initial prospecting in regions such as the Democratic Republic of the Congo, but commercial lenders abandon projects during costly feasibility studies.

This capital shortage creates a developmental "valley of death" before mine construction. Mines take roughly 20 years to build. China systematically exploits this financing vulnerability by offering equity and state-backed loans, spending a record $32 billion on metals and mining through the Belt and Road Initiative in 2025. Consequently, Chinese enterprises secured control over 70 percent of Congolese copper and cobalt mines. While Washington announced $50 billion in mineral investments, signing $9 billion and disbursing $4 billion, public funds focus almost exclusively on near-production refining facilities rather than high-risk, early-stage resource extraction infrastructure.

Comment

Chinese state equity acquisition in projects like the Kamoa-Kakula copper complex demonstrates how Beijing absorbs pre-commercial extraction risks that Western private capital rejects. When Canadian-listed Ivanhoe Mines failed to secure Western venture backing for feasibility studies, Zijin Mining stepped in to finance the project's transition into active production. This institutional risk aversion in Toronto and New York leaves Western defense industrial capacity exposed to off-take agreements controlled by battery conglomerates like CATL.

Japan faced this operational vulnerability following Beijing's 2010 rare earth export restriction during the Senkaku Islands dispute. Despite subventing Australian miner Lynas Rare Earths through Japan Energy and Metals National Corporation for fifteen years, Japanese industrial dependence on Chinese processing still hovers near 70 percent.

Strategic Question for Discussion

If state-backed entities like Zijin Mining continue capturing equity stakes at the feasibility stage, can public financing mechanisms like Japan Energy and Metals National Corporation effectively insulate downstream defense supply chains, or does Western commercial risk aversion make raw material dependence permanent?

The trajectory indicates that public subventions through vehicles like Japan Energy and Metals National Corporation can mitigate specific processing bottlenecks, but cannot fully compensate for systematic private-sector risk aversion during early-stage exploration. While targeted state loans prevent complete reliance on Chinese refining, the long lead times of mining development mean off-take agreements will remain heavily skewed toward Beijing-backed conglomerates. Consequently, sovereign risk-mitigation initiatives will likely produce only partial supply security rather than total autonomy across critical mineral inputs.
