During his confirmation hearing before the Senate Armed Services Committee, Randall Schriver said that the US needs to look for opportunities to work with China wherever American interests overlap.
"We must also recognise that their aspirations, their vision for the future security architecture of the Asia- Pacific region with China at the centre is, in many ways, at odds with our own aspirations," he said.
"For this administration's vision for a free and Indo- Pacific to be realised we also have to deal with the rising challenges presented by China," he added.
Senator Jack reed said that while the US must work together with China to counter a nuclear threat from North Korea, it should also work to counter China's attempts to "bully its neighbours in the region" and its failure to abide by the rules-based international order from which it has benefited so greatly.

"The Administration is rightly focused on ensuring a free and open Indo-Pacific region, while also addressing specific challenges, such as those posed by North Korea, managing a rising China and its increasingly assertive attempts to undermine the rules-based order, building stability in South Asia, and confronting the scourge of terrorism wherever it emerges," he said.
"We will not accept Chinese actions that undermine the rules-based order. If confirmed, I will assess the effects of China's growing influence in the region, including on the US security posture, to ensure we are able to maintain the presence and posture that have underpinned US security guarantees, and in turn, regional peace and prosperity for decades," he said.

"I believe the theft of intellectual property through cyber means is a clear threat to the economic prosperity from which in large measure the nation derives its national security.
John C Rood nominee for Under Secretary of Defense for Policy said that China is a long-term strategic competitor, engaged in a rapid, comprehensive military modernisation process.
China's military reforms seek to enhance its ability to conduct joint operations and improve its ability to fight high-intensity regional conflicts at greater distances from the Chinese mainland.
China's global interests are growing, and its military will increasingly be called upon to safeguard China's trade, investments, and citizens abroad, he said.
