Ministers from the US, EU, UK, Japan, Australia and New Zealand will meet in Washington this week to discuss a strategic alliance over critical minerals.
One area of discussion will be calls for the US to guarantee a minimum price for critical minerals and rare earths.
Canberra’s resources minister, Madeleine King, said a US decision not to offer minimum pricing “won’t stop Australia from pursuing our critical minerals reserve programme”.
A UK minister will attend, the Foreign Office said, adding: “UK economic security goes hand in hand with national security.
That’s why we are working to ensure a diversified critical minerals supply chain – a vital step to securing economic growth in the UK.
