The US "pivot" to the Asia-Pacific, including the country's expanding military presence and consolidation of military alliances, has destabilized the region, according to a Ministry of National Defense report issued on Tuesday.

Military experts said Beijing has no problem with Washington seeking involvement in the region's prosperity, but it is concerned that the US initiative might be aimed at China and disturb the "Chinese dream" of national rejuvenation.

"Some countries are strengthening their Asia-Pacific military alliances, expanding military presence in the region, and frequently making the situation there tenser," the 40-page report on the "Diversified Employment of China's Armed Forces" said, without naming any particular state.
