A 10-member Chinese delegation left Beijing Friday morning, to observe a large-scale U.S. military exercise, at the invitation of Admiral William J. Fallon, commander of the U.S. Pacific Command.

As part of exchanges between the two armies, the visit is good for the two sides to promote mutual understanding and trust, said a spokesman of the Ministry of Defense, adding that it also helps the two sides to learn from each other and promotes the development of the two armies.
