China's new export restrictions on rare earth materials are causing alarm in Europe, particularly within the defense industry, which is urged to enhance supply chain resilience. The Aerospace, Security and Defence Industries Association of Europe (ASD) is monitoring the situation closely, as these restrictions could severely impact ammunition production and high-tech systems. Europe is striving for greater defense autonomy amid rising tensions with Russia and is working on strategies to reduce dependence on foreign suppliers. However, experts warn that achieving this will be challenging and time-consuming.
