Britain and Japan Lock In £18 Billion Investment Partnership

Britain and Japan are finalizing an £18 billion investment and technology partnership—among the UK's largest bilateral deals post-Brexit. Building on their 2023 trade agreement, this co-investment ties government and corporate priorities across semiconductors, defence, green energy, and digital sectors. For London, it rebuilds trade relationships outside Europe; for Tokyo, it deepens ties with democratic allies while managing regional geopolitical risk.
