President Joe Biden arrived here Friday on a mission to reaffirm a key alliance at an uncertain moment in East Asia.

Even as the war in Ukraine has preoccupied Washington — and took up the first half of Biden’s day before he departed for Asia — provocations from North Korea have intensified and China continues flexing its economic and military might.
Biden wants to show his top partners here he can focus both eastward and westward, and that the United States has resources to help uphold democracy and sovereignty around the world.
