WASHINGTON -- It's up to Vice President Joe Biden to show that the U.S. effort to focus more on Asia hasn't fizzled out.
Biden is set to arrive Monday in Tokyo on a trip to Asia. The region is watching carefully to see how committed the Obama administration is to increasing America's influence there.
Biden will meet with leaders in Japan, China and South Korea.
He'll try to show that while the administration has paid great attention to Mideast flare-ups and dealt with a series of domestic distractions, the U.S. still intends to be a Pacific power.
At the same time, several disputes among Asian nations seem to be boiling over, threatening instability in the region. And now China has declared a new maritime air defense zone over the East China Sea.
