Capabilities growth shows why US sees China as pacing challenge

The chairman of the Joint Chiefs of Staff spoke on Bloomberg News' David Rubenstein Show and said DOD officials saw the test as "a very significant event."

Pentagon Press Secretary John F. Kirby emphasized that China's development of a wide range of systems and capabilities paired with their aggressive foreign and economic policies are clearly why Secretary of Defense Lloyd J. Austin III sees China as America's pacing challenge.

Kirby noted the Chinese capabilities "do very little to help decrease tensions in the region and beyond."

The hypersonic test is just one part of a suite of security issues with respect to China. Kirby said DOD leaders are concerned about the trajectory of where things are going in the Indo-Pacific region. This suite "taken together [is a] reason for concern and [is] being used to inform the operational concepts that we want to be able to employ," the press secretary said.

"They're informing the budget. They're informing the programs and the priorities of the department. They're going to inform ... our training and exercise regimen."

A free and open Indo-Pacific remains a key national security goal for the United States, Kirby said, and DOD has a significant role in that effort. He said China's actions are factored into deliberations on the global posture review and will be factored into the National Security Strategy and National Defense Strategy next year.

Milley emphasized the same in his talk. He noted the Chinese are expanding rapidly in all domains of warfare - land, sea, air, cyber and space. "They have gone from a peasant army that was very, very large in 1979 to a very capable military that covers all domains, and has global ambitions. China is very significant on our horizon."
