U.S. President Barack Obama on Wednesday assured a visiting senior Chinese military officer that his administration is committed to building an active, cooperative and comprehensive relationship with China, which requires both strong bilateral diplomatic ties and strong two-way military ties.

　　Obama made the remarks while meeting Xu Caihou, vice chairman of China's Central Military Commission, at the White House. The U.S. president pledged to try his best to promote the military-to-military ties.
