Kishida is in Washington on the last stop in a tour of the G7 industrial powers and has been seeking to bolster long-standing alliances amid rising concern in Japan, and the United States, about mounting regional security threats.

In a meeting at the White House, Biden called it a "remarkable moment" in the US-Japan alliance. 

Kishida said that "Japan and the United States are currently facing the most challenging and complex security environment in recent history." He said Tokyo had formulated its new defense strategy released last month "to ensure peace and prosperity in the region."
