D\u00c9CRYPTAGE – <\/strong>En soutenant la compagnie mini\u00e8re am\u00e9ricaine MP Materials, le d\u00e9partement de la D\u00e9fense a fait bondir le cours d\u2019un alliage crucial et fragilise – un peu – l\u2019h\u00e9g\u00e9monie de P\u00e9kin.<\/p>\n

L\u2019Occident parviendra-t-il \u00e0 mettre fin \u00e0 la domination chinoise, planifi\u00e9e et organis\u00e9e de longue date, sur les\u00a0terres rares<\/a>, cette famille de minerais indispensables aux nouvelles technologies\u00a0? L\u2019enjeu est crucial. Et son r\u00e9sultat tr\u00e8s incertain alors que la Chine domine la cha\u00eene d\u2019approvisionnement mondiale, avec 70\u00a0% de la production mini\u00e8re, 90\u00a0% de la capacit\u00e9 de raffinage et 95\u00a0% de la\u00a0production des aimants permanents<\/a>, cr\u00e9\u00e9s \u00e0 partir de ces m\u00e9taux.<\/p>\n

Des promesses de milliards de dollars<\/p>\n

Une mesure r\u00e9cente du gouvernement am\u00e9ricain, qui est pr\u00eat \u00e0 d\u00e9bourser des milliards pour contrer l\u2019h\u00e9g\u00e9monie chinoise, produit des effets in\u00e9dits. Washington a conclu le 10\u00a0juillet un accord avec le principal producteur am\u00e9ricain de terres rares, MP Materials. Celui-ci s\u2019est engag\u00e9 \u00e0 cesser d\u2019envoyer les minerais extraits en Chine pour les y faire raffiner et \u00e0 r\u00e9aliser au contraire cette op\u00e9ration sur le sol am\u00e9ricain.<\/p>\n
