(ANSA) - BRUSSELS, 04 DIC - "Today, the production and processing of some of the critical raw materials for the green revolution are controlled by a single country, China. Europe and the United States can build an alternative to this monopoly by establishing a critical raw materials club. The idea behind it is simple: cooperation with partners and allies in sourcing, production, and processing gives us a chance to overcome the monopoly." European Commission President Ursula von der Leyen said in a speech in the Belgian city of Bruges. (ANSA).
