The meeting also included discussions of the current defense environment facing the United States and Japan and included typical references to the threat posed by China, North Korea, and Russia; defend Taiwan; and the common interests and values ​​that America and Japan share.

According to Secretary Austin:

“We also share a vision of a free and open Indo-Pacific and a rules-based international order. But China’s recent aggressive behavior and Russia’s unprovoked invasion of Ukraine are serious challenges to this vision. […] Let’s be clear, China’s coercive actions in the Taiwan Strait and the waters surrounding Japan are provocative, destabilizing and aggressive. Our response, together with Japan and our other allies and partners, has been responsible, steady and resolute. »
