Donald Trump has moved the war for critical minerals from the margins of policy to the heart of great power rivalry. In this episode of Battle Lines, we look at Project Vault, America's bid to take back control of the critical minerals and rare earths supply chain from China. 

This bid to build a vast new stockpile and industrial strategy was unveiled at the inaugural US Critical Minerals Ministerial Summit last week. Supporters see it as a necessary first step to protect American industry and national security. Critics warn that for middle countries, it may simply shift dependencies rather than break them.

Venetia talks to Sibylline Chief Analyst Sam Olsen to unpack what Project Vault really means, why processing matters more than mining, and how China has weaponised its dominance in ways OPEC never could. 

Plus, a deep dive on how Greenland fits into the West's rare earths strategy. Greenland Energy, Business and Mineral Resources Minister Naaja Nathanielsen on that Trump deal, Chinese influence and the challenges of mining on the island.
