Britain and Japan on June 14 agreed a broad economic and technology partnership expected to generate more than GBP18bn ($24bn) in investment, AFP reports.
As part of a visit to London by Japanese Prime Minister Sanae Takaichi, UK Prime Minister Keir Starmer held talks with his counterpart at Downing Street ahead of a G7 summit in France starting on June 15.
More than 10 trade agreements were signed in total. These included an offshore wind farm project. Starmer described the deal as marking “a new era of cooperation between our two countries”.
The leaders also attended a roundtable with business representatives from both countries.
The partnership includes deeper cooperation between Rolls-Royce and the Japan Atomic Energy Agency.
Both sides also announced plans to launch the UK-Japan Frontier Tech Partnership (FTP). The initiative aims to translate British research into scalable technologies with Japanese investment, including in artificial intelligence and semiconductors.
A formal production agreement will link the British Semiconductor Centre with Japanese chipmaker Rapidus.
On defence, the two leaders reaffirmed support for the Global Combat Air Programme (GCAP). The project aims to develop a next-generation supersonic fighter jet. Starmer said it remained central to bilateral ties.
GCAP was launched in 2022 by Britain, Italy and Japan, with a target of delivering a new combat aircraft by 2035 to replace the Eurofighter Typhoon.
Total trade between the UK and Japan is currently worth around GBP140bn, according to the UK government.
