Rare earths

This Sunday's dossier is dedicated to rare earths. We've talked a lot about this these past few days, because the United States and Ukraine have finally signed an agreement to exploit them. These critical materials are now the new oil, and the global race to control them has begun. Let's review the conflicts around the world caused precisely by these materials, from Africa to Greenland. We'll also explain exactly what materials we're talking about from a geological perspective and what they're used for.
