China has placed ten US companies on its export control list, targeting firms in the defence, aerospace technology, and rare earths sectors.
The move, reported by multiple wire services, marks a direct escalation in the ongoing trade dispute between Beijing and Washington.
The restrictions are justified by Chinese authorities as a response to the companies' links to the US military.
By broadening the scope to include rare earths and aerospace technology, Beijing is signaling a willingness to leverage critical supply chain nodes in its strategic competition with the United States.
This development adds to a pattern of reciprocal trade measures.
Previous rounds of export controls have already disrupted supply chains for US defence contractors and technology firms reliant on Chinese components.
