U.S. Adm. Mike Mullen, chairman of the Joint Chiefs of Staff, left, arrives on a Chinese military aircraft at the 1st Mechanized Infantry Division of the PLA in Hangzhou, eastern China, Tuesday, July 12, 2011. The top U.S. military officer is on a visit, the first of its kind in four years as the two governments are trying to improve military-to-military ties after setbacks over U.S. arms sales to Taiwan, cyberattacks traced to China and concern about Beijing's military plans.
