Critical minerals: The global race is on

They’re essential to the green transition, modern tech, and defence systems—and global demand is soaring. In the first part of our series on critical minerals, we ask what they are, where they're found and why they matter? As countries scramble to secure supplies, we explore the rising geopolitical tensions shaping this fast-growing industry—including the Oval Office standoff between Presidents Trump and Zelensky over a landmark minerals deal.
