China has imposed export controls on ten US companies specializing in defense and rare earths mining. This action serves as a direct response to a blacklist previously issued by Washington. Additionally, Beijing has banned public procurement from dozens of other American firms. These measures follow a recent visit to Beijing by US President Donald Trump. During that trip, Trump met with President Xi Jinping to discuss stabilizing the strained relations between the two nations. The new restrictions highlight the ongoing tension despite diplomatic efforts to reduce friction. The move underscores the strategic importance of rare earth minerals in the current trade conflict.
