Tokyo, 14 June 2026 – Japan is seeking to place critical-mineral security at the centre of the upcoming G7 summit, with Prime Minister Sanae Takaichi reportedly proposing a coordinated stockpiling framework aimed at reducing exposure to export disruptions.
The proposal comes as advanced economies grow increasingly concerned about access to rare earths and other critical minerals used in semiconductors, electric vehicles, renewable energy, defence systems and high-performance electronics. These materials have become central to the global technology race, making supply-chain security a strategic priority for governments and corporations.
