"China is developing military capabilities that make it much more difficult for the United States to access hot spots in the region and, therefore, to meet its various defense commitments which have underguarded security order in the region for half a century," he said.
Beijing has deployed various classes of destroyers with cruise missiles that can fire upon US carrier battle groups, "which is a matter of great concern," he said.
In addition, Blumenthal said, China's deployment of diesel submarines made it "much more difficult and complicated for US carrier battle groups to get into areas that they need to get into."
China is also accused of using its manned space program to achieve its military ambitions.
"Every mission performed either electronic or military surveillance for the PLA [People's Liberation Army] but China is loathe to admit, from the very inception, that its manned space program has directly served military purposes," Fisher said.
Brookes said that the US' immediate concern is that China will try to use its new military might on Taiwan to effect unification. Also, China has as many as 750 ballistic missiles aimed at Taiwan, according to the Pentagon. Many of them are reportedly also capable of striking US forces stationed in Japan.
