Biden: US "Deeply Concerned" By Chinese Air Defense Zone That Extends Over Disputed Islands

New zone to dominate talks during the vice president's trip to Asia

|

The US remains "deeply concerned" about China's new air defence identification zone (ADIZ), Vice-President Joe Biden said as he began a tour of East Asia.

In written responses to Japan's Asahi newspaper, Mr Biden said China and Japan had to establish measures to lower tensions.

Mr Biden arrived in Tokyo late on Monday and will then head to Beijing and Seoul during his six-day visit.

The air zone row is likely to dominate the week of talks.
