China on Monday imposed immediate export controls on ten American defence and rare earth companies and barred government agencies from purchasing products from 46 US firms, retaliating directly against the Pentagon’s addition of Chinese technology groups to its military-linked blacklist earlier this month. The dual measures, which took effect the same day, require Chinese exporters to halt all shipments of dual-use items to the listed entities and prohibit public procurement from major contractors including Lockheed Martin, Raytheon and Boeing’s defence division.

The Commerce Ministry’s export control list targets firms with direct US military ties: Aveox holds aerospace defence contracts, Oshkosh Defense produces military vehicle fleets, and MP Materials operates the only active rare earth mine in the United States. The ban extends beyond Chinese exporters to any organisation or individual in third countries transferring Chinese-origin dual-use goods to the designated companies. The Finance Ministry’s parallel procurement prohibition exempts US-invested enterprises operating within China, but otherwise blocks state buyers from acquiring products from a broad swath of the American defence-industrial base.

Analysts in Washington and Asia assess the export controls as a largely symbolic but proportionate response. George Chen of The Asia Group noted that most listed firms are US defence industry players with negligible commercial ties to China, limiting the direct economic impact. However, the inclusion of rare earth producers MP Materials and USA Rare Earth carries strategic weight, given China’s dominance of global rare earth processing and its willingness to weaponise supply chains. The procurement ban, while similarly limited in immediate commercial effect, reinforces Beijing’s message that it will mirror US restrictions.

The escalation follows a brief diplomatic thaw: Donald Trump visited Beijing in May, and both sides agreed to work towards tariff reductions. Yet within weeks, Washington updated its “Chinese military enterprise list” to include Alibaba, Baidu, BYD and NIO, alleging they support the People’s Liberation Army. Beijing had previously sanctioned several of the same US firms in 2024 and 2025 over arms sales to Taiwan, and the US is now reviewing a proposed $14 billion weapons package for Taipei. The cycle of sanctions highlights the persistent friction in technology and defence, even as trade negotiations continue.

The next concrete milestone is the end of June, when US law will bar the Department of Defense from directly contracting with companies on its blacklist, with a broader ban on third-party purchases to follow in 2027. China’s latest move signals that it will continue to calibrate export restrictions, particularly in rare earths, as a countermeasure. The Taiwan arms review decision remains another near-term trigger for potential further action.
