It's a decade after Barack Obama announced a "pivot to Asia". Successive US administrations have talked about China's growing economic, diplomatic and military clout.

But troubles elsewhere have obscured the planned focus on Beijing, and now the U.S. is stepping up support for Ukraine in its war with Russia.
Is that conflict challenging the United States' long-sought strategic and economic shift to Asia, as Joe Biden
makes his first visit to the region as president?
