Historic UK–Japan cooperation key to Indo-Pacific stability
“Other examples of the relationship’s expansion include the 2022 announcement of UK–Japan–Italy collaboration on the Global Combat Air Programme, Japan’s first partnership with a country other than the United States to build a major defence capability.”
“In March 2025, the first UK–Japan ‘Economic 2+2′ ministerial meeting took place involving the United Kingdom’s foreign secretary and business and trade secretary, and their Japanese counterparts.”
“Japan and the United Kingdom are the two largest economies in the CPTPP by a large margin, with the United Kingdom bringing a strategic economic depth in services and intellectual property. Japan also hopes that the United Kingdom’s presence in the CPTPP will help it to manage the geopolitical challenge of China and Taiwan both wanting to join the bloc.”
“The United Kingdom’s CPTPP accession also adds an economic pillar to their strategic presence. London is also an ASEAN Dialogue Partner and signatory of the AUKUS agreement.”
