TOKYO/WASHINGTON (Reuters) - U.S. Vice President Joe Biden will seek a delicate balance between calming military tensions with China and backing ally Japan against Beijing on a trip to Asia this week that is being overshadowed by a territorial row in the East China Sea.
Japan reiterated on Monday that Tokyo and Washington had both rejected Beijing's move to set up an air defence zone that includes islands at the heart of a bitter Sino-Japanese feud - despite the fact that three U.S. airlines, acting on government advice, are notifying China of plans to transit the zone.
