Japan and UK strengthen ties in defense, economy, and technology.

Japan and the UK have signed a new agreement to deepen security ties, including a UK commitment to deploy an aircraft carrier strike group to the Indo-Pacific in 2025. The agreement, called the "Hiroshima Accord," will also cover trade and investment, collaboration on science and technology, and joint initiatives to tackle global issues such as climate change. The move comes amid heightened tensions in the Asia-Pacific over North Korea and China's increasingly assertive positions on issues such as Taiwan and the disputed South China Sea.
