UK and Japan sign Frontier Technology Partnership backed by £18B in bilateral investment
Prime Ministers Starmer and Takaichi signed the Frontier Technology Partnership on June 14, anchored by an £18B package — £9B in Japanese corporate investment across UK infrastructure and financial services, and up to £9B in offshore wind. The deal formalizes mutual dependency on AI, semiconductors, quantum, and critical minerals, with GCAP as the defence anchor and explicit coordination mechanisms on economic coercion and export-control responses.
