Chinese exporters are blocking rare earth shipments to the United States due to fears of retaliation from Beijing.. This supply chain squeeze comes just before President Xi Jinping's scheduled Washington visit on September 24.
The Busan and Beijing Truce under Pressure
The current disruption in mineral exports represents a breakdown of previous diplomatic efforts to stabilize trade. According to the report,American officials have pushed for the adherence to agreements reached in Busan and Beijing, which were designed to ensure that export licenses for critical materials remained predictable and stable.
However, this stability has been eroded by a cycle of retaliation. The Chinese government argues that its current restrictions are a defensive response to actions taken by the Federal Communications Commission (FCC). Specifically, the FCC has implemented restrictions targeting Chinese drones, consumer routers, advanced robotics equipment, and electronics testing labs, which Beijing views as a violation of the Busan truce.
How RBA Sanctions Chilled Supplier Confidence
A primary driver of the current export halt is the Chinese government's decision to sanction the Responsible Business Alliance (RBA). as the source notes, the RBA is a U.S.-based supply chain monitor closely linked to the Responsible Minerals Initiative, which establishes global auditing frameworks for ethical mineral sourcing.
This has placed Chinese suppliers in a precarious position. Because these firms fear that complying with RBA auditing standards could be seen as adhering to foreign-imposed due diligence—and thus violating Chinese national interests—many have chosen to unilaterally stop exports. These suppliers would rather lose American customers than risk the wrath of the central government in Beijing.
Yttrium and Tungsten: The High Cost of Military-Grade Minerals
The impact of these restrictions is most acute for materials essential to national security, such as tungsten, indium phosphide, and yttrium. These elements are indispensable for semiconductor chips, aerospace components, and precision-guided weapon systems, and their prices remain near record highs due to the tightened supply.
The strategic nature of these halts is evident in the data. While China continues to ship minerals to other global partners, Chinese customs data indicates that yttrium exports to the United States are currently only about half of the volume recorded in 2024. This selective restriction suggests a deliberate weaponization of the supply chain targeting the U.S. specifically.
Will the September 24 Summit Break the Deadlock?
There are signs that Beijing may be using these restrictions as a bargaining chip ahead of President Xi Jinping's visit to Washington on September 24. Some industry insiders believe China might loosen controls shortly before the summit to deflect U.S. accusations that it is ignoring international commitments.
There is some evidence of a tentative thaw; the U.S. received 27 tons of yttrium in July, marking the second-highest monthly shipment since January 2025 after two months of zero exports. However, significant questions remain regarding the longevity of this relief. It is unclear if the sudden influx of license approvals reported by some U.S. companies is a permanent shift or a temporary diplomatic gesture. Furthermore, the report highlights that buyers in India and Japan are facing even more severe hurdles, with Japanese Trade Minister Ryosei Akazawa noting prolonged permit delays and customs inspections.
