China announced on Tuesday that it will halt exports to Japan of materials that could potentially be utilized for military applications, heightening tensions with a significant U.S. ally amid ongoing disputes concerning Taiwan. This decision was confirmed by China’s Ministry of Commerce, which indicated that items with dual civilian and military uses will no longer be exported to Japan.
Details regarding which specific items are included in the ban were not disclosed. However, state media suggested that the Chinese government might consider rare earth minerals as part of this restriction.
Japanese leadership has increasingly connected Taiwan’s situation with its own national security. Recently, Prime Minister Sanae Takaichi expressed concerns that China’s actions against Taiwan could pose an “existential crisis” for Japan, potentially justifying military response under its self-defense legislation.
In his New Year’s address, Xi Jinping emphasized that the “unification” with Taiwan is “unstoppable,” which coincided with China’s live-fire military exercises simulating a blockade of Taiwan.
This recent export ban draws parallels to a similar incident in 2010 when China suspended rare earth exports to Japan for almost two months due to a territorial dispute.
The rare earths conflict served as an early indication of China’s readiness to utilize trade as a strategic weapon, prompting U.S. defense strategists and allies to review the reliance of military supply chains on Chinese resources. Although there have been efforts to diversify sourcing, China still dominates several crucial commodity sectors.
China currently holds around two-thirds of the world’s rare earth mining operations and the majority of processing capabilities, a situation that led the Trump administration to focus on diversifying supply chains and revitalizing domestic production for national security reasons.
For a long time, Washington has allowed rare earths to remain mostly unregulated on the market, despite the closure of U.S. mines and a shift of production to China. However, the Trump administration signaled a notable policy shift by deploying Pentagon funding to support MP Materials at California’s Mountain Pass mine, marking a direct governmental effort to restore rare earth processing capabilities deemed vital for modern military systems.
