The United Kingdom released its “Integrated Review of Security, Defence, Development and Foreign Policy” on 16 March 2021. Titled ‘Global Britain in a Competitive Age’, the document stands out for shaping the country’s post-Brexit foreign, defence, security and development priorities and policies. A notable aspect of the review is the UK’s foreign and security policy ‘tilt’ towards the Indo-Pacific region. China, India and Japan are recognised as the three most important powers in this region with widely differing characteristics and relationships with the UK.
