Japan's Prime Minister Kishida Fumio and US President Joe Biden are likely to reaffirm their policy of strengthening the bilateral alliance when they meet on the sidelines of the Group of Seven summit in Hiroshima.
The summit begins on May 19. In addition to the G7 nations, leaders of eight countries and representatives of seven international bodies are invited to the summit. They include Indian Prime Minister Narendra Modi, who chairs the Group of 20 economies.
Arrangements are underway for Kishida to hold one-on-one talks with Biden, Modi and other participants.
Kishida and Biden are expected to reaffirm the need to bolster deterrence and response capabilities of the alliance in light of China's growing assertiveness and North Korea's repeated ballistic missile launches.
The two leaders are also likely to discuss ways to strengthen supply chains for important minerals and advance negotiations on the Indo-Pacific Economic Framework in which their countries participate.
India is seen as a leader of the emerging and developing economies collectively known as the Global South.
When Kishida meets Modi, they are expected to confirm that they will collaborate as the chairs of the G7 and G20.
Foreign Minister Hayashi Yoshimasa is considering holding talks with representatives of the international organizations.
The government hopes those meetings will facilitate the sharing of its stand on keeping and strengthening the rules-based international order.
