The growing entanglement of national security, technological supply chains and financial sovereignty is profoundly changing global macroeconomic balances. Financial markets and the crypto ecosystem were observing signs of institutional stabilization when a major diplomatic rupture just occurred. This Monday, June 22, China officially ended the trade truce by announcing massive sanctions against dozens of American companies linked to the strategic sectors of defense and rare earths. Beijing's offensive reignites economic hostilities with Washington and threatens to stifle high-tech industries that depend on these raw materials essential to advanced infrastructure.
In brief
- China abruptly ends the trade truce with the United States by announcing a series of sanctions targeting American companies active in defense, robotics and rare earths.
- Beijing bans the export of dual-use products to several strategic American companies, increasing pressure on sectors heavily dependent on Chinese supply chains.
- A second wave of measures hits Chinese public markets, with the exclusion of dozens of American aerospace, defense and advanced technology companies.
- This escalation marks the breakdown of diplomatic efforts initiated for several months between Washington and Beijing, despite recent discussions on rare earths and bilateral trade.
Beijing's retaliation: China's blockade on dual-use technologies
While a trade agreement between China and the United States has revived optimism, Beijing's decision directly responds to Washington's regulatory offensive, launched in early June 2026 when the Pentagon expanded its blacklist by adding Chinese technology giants Alibaba, Baidu and BYD, under the label “Chinese military companies” operating on American soil. The Chinese Ministry of Commerce strongly denounced this initiative, calling it “unconscionable act of the American government”. To respond immediately, the ministry put ten American companies and entities on a list purely and simply prohibiting the export of products that could be dual-use, civil and military.
China has published a strict instruction: “No organization or individual, regardless of country or region, is permitted to transfer or provide dual-use items from China to these entities”. In order to avoid any transition, the central government also demanded that “any ongoing export activity must cease immediately”.
Among the ten entities affected by this decree are key players in the technological ecosystem, robotics and the supply of critical minerals:
- USA Rare Earth: a strategic company committed to developing an independent domestic supply chain for permanent magnets and rare earth processing in the United States;
- Red Cat: a manufacturer specializing in the development of tactical drones and advanced robotic systems;
- AVEOX: a designer of high-power electromechanical systems essential to critical motorization technologies.
By targeting these specific companies, China, an influential member of the BRICS alliance, intends to cripple the innovation and manufacturing capacity of subcontractors of the American military-industrial complex, who are dependent on its hegemony in the refining of rare earths. The neutral and strictly executive tone of official Chinese declarations shows an intention to impose unfailing administrative rigor, transforming the currents from essential components into real instruments of political pressure.
The embargo on public procurement and the collapse of the Sino-American truce
The punitive arsenal implemented by Beijing goes beyond just export restrictions on raw materials to aggressively extend to public markets through a second directive, this time from the Chinese Ministry of Finance. This part expressly prohibits Chinese public administrations, ministries and local authorities from purchasing technologies and equipment from forty-six American companies.
The Ministry of Finance inserted this rule in a decree clearly stating that “Buyers cannot acquire manufactured products” by these specific companies. This retaliatory measure directly targets the specialized divisions of aerospace and arms giants, including Lockheed Martin, Raytheon, the space, defense and security branch of the Boeing group, as well as subsidiaries of General Dynamics and the aircraft manufacturer Sierra Nevada Corporation.
Such a rise in regulatory power marks the sudden collapse of a relative lull which had lasted since October 2025, marked by intense bilateral negotiations to reduce customs duties on tens of billions of euros of goods. This suspension comes barely a month after President Trump's official visit to China, when Beijing had committed to examining the “legitimate concerns” of Washington on the security of supplies of rare earths.
Diplomatic preparations also included an official invitation from President Xi Jinping to a summit in Washington scheduled for next fall. This de facto cancellation of these economic compromises shows that Beijing prefers to defend its technological flagships in the face of Pentagon sanctions, even if this means sacrificing short-term trade agreements.
Macroeconomic implications and new sovereignty perspectives
This freeze in trade calls into question the long-term resilience of Western supply chains and the stability of global markets. Lacking direct access to the critical minerals needed to manufacture semiconductors and supercomputers, American high-tech companies will have to accelerate the development of complex and expensive industrial alternatives.
This increased geopolitical fragmentation could amplify the volatility of traditional capital markets for the overall financial ecosystem and decentralized technology sector, pushing fund managers to reassess their asset allocation in the face of unpredictable regulatory risks.
This crisis reveals the birth of a bipolar world where computing infrastructures, from artificial intelligence to highly secure data processing, find themselves held hostage by conflicts between States. Opinions differ on the West's ability to quickly catch up industrially without resorting to Chinese refining capacities.
Some experts fear a prolonged inflation of advanced electronic components in this Chinese counterattack, while others see it as a historic opportunity for relocation. With the ever-present risks of cross-sanctions, administrative exclusions and blockages of centralized monetary flows, the need to have resilient architectures, alternative supply networks and reserve assets independent of state decisions appears more than ever as a central subject of strategic reflection for the years to come.
