Nerastné suroviny Vietnamu Vietnam je bohatý na nerastné suroviny, ktoré sa nachádzajú prevažne na severe krajiny. Ložiská bauxitov, fosfátov, vzácnych zemín (REE), majú svetový význam. Ale i zásoby celého radu ďalších surovín (ropy, uhlia, zlata, železných rúd, chromitu, cínu, ilmenitu, medi, grafitu, atď.) sú významné, ekonomicky ťažiteľné a ich potenciál je obrovský. Za uvedené nerastné bohatstvo je „zodpovedná“ rozmanitá geologická stavba krajiny. Taktiež i morfológia a klíma (vlhk…
