China clears limited rare earth exports to Japan under tighter ‘dual-use’ controls

In a delicate balancing act between economic leverage and global supply chain stability, Beijing has begun green-lighting a selective batch of rare earth exports to Japan. The move follows a period of intense diplomatic friction and serves as the first major test of China’s newly implemented “dual-use” export control regime.

While the approvals offer a temporary sigh of relief for Japanese manufacturers, they come tethered to a significantly more rigorous and granular screening process that signals a “new normal” in Arctic and high-tech trade relations.

The export clearances come after China earlier this year imposed new restrictions on certain rare earth elements and related products, requiring exporters to seek government permission before shipping them overseas. Japanese companies have confirmed that while some export licences have been granted, the process has become slower, more opaque and subject to closer scrutiny than before. Volumes, meanwhile, remain below previous levels, highlighting the lingering uncertainty facing manufacturers dependent on these critical inputs.

The civilian safety valve: Approvals amidst restrictions

Chinese commerce officials confirmed this week that while the ban on dual-use items for military purposes remains absolute, “compliant” applications for civilian end-use are being processed. This distinction is critical for Japan, which remains approximately 72 per cent dependent on Chinese rare earths to fuel its automotive and electronics sectors.

By approving these specific shipments, Beijing is attempting to demonstrate that it is not enforcing a blanket embargo similar to the one seen during the 2010 Senkaku Islands dispute. Instead, it is utilising a targeted “licensing” strategy.

These approvals primarily cover materials destined for household electronics and standard automotive parts- industries that, while economically vital, are categorised as low-risk for military enhancement. However, the “timely approval” promised by Beijing comes with a caveat: Japanese firms must now provide unprecedented transparency into their supply chains, including the final destination of any re-exported components.

The “dual-use” barrier: A strategic squeeze

Despite the recent approvals, the shadow of the January 6 dual-use ban looms large over the bilateral relationship. The tightened controls are largely seen as a retaliatory strike against Japanese Prime Minister Sanae Takaichi’s recent comments regarding Taiwan’s security.

Under the current framework, “heavy” rare earths such as dysprosium and terbium face the strictest scrutiny. These elements are indispensable for the high-performance magnets used in both electric vehicle (EV) motors and precision-guided missile systems.

The new administrative hurdles require Japanese importers to submit detailed documentation covering downstream customers and intermediaries. For many Japanese firms, this level of disclosure is fraught with risk, potentially exposing proprietary trade secrets to Chinese regulators.

Economists at the Nomura Research Institute warn that even with these selective approvals, any prolonged delay in the shipment of heavy rare earths could result in production losses exceeding ¥2.6 trillion ($17 billion) annually, effectively shaving 0.43% off Japan’s GDP.

Japan’s counter-strategy: Diversification and deep-sea hopes

The uncertainty surrounding Chinese export permits has accelerated Japan’s quest for mineral independence. Just as the export approvals were announced, Japan made a historic breakthrough in domestic resource acquisition. The deep-sea drilling vessel Chikyu successfully retrieved rare-earth-rich mud from a depth of 6,000 meters near Minamitorishima Island, a world first that Prime Minister Takaichi hailed as a “first step toward industrialization.”

While commercial production from the seabed is not expected until at least 2027, the psychological shift is already underway. Japan is increasingly looking toward trilateral partnerships with the US and the EU to coordinate procurement and build “resilient supply chains” that bypass Chinese processing dominance.

For now, the limited flow of Chinese rare earths acts as a vital bridge, keeping Japanese assembly lines moving while Tokyo races to ensure that its high-tech future is no longer held hostage by the shifting winds of Beijing’s trade policy.
