Rishi Sunak, the UK prime minister, and his Japanese counterpart, Fumio Kishida, will on Wednesday sign a defence agreement, enabling the UK and Japan to deploy forces in each other’s countries.
The move comes as the UK government seeks to strengthen its engagement in the Asia-Pacific region to counter the influence of China, although the war in Ukraine has forced London to reassess its global strategy.
The talks in London will also see the two leaders discuss Britain’s bid to join the Comprehensive and Progressive Agreement for Trans-Pacific Partnership, a free trade bloc that includes Japan, Canada, Mexico and Chile, in spite of reservations from some Conservative MPs.
