It is in US' interest to accept China's rise
Engaging with China has always been a political compulsion for US administrations. Former US president Barack Obama's "pivot to Asia" strategy and incumbent President Donald Trump's "Indo-Pacific" strategy suggest the United States will increase its presence in Asia. Though the "Indo-Pacific" strategy is still a work in progress, it is set to pose new challenges to the China-proposed Belt and Road Initiative, and regional cooperation as a whole.
The foremost of those challenges is the Democratic People's Republic of Korea's nuclear issue, where China and the US still have much room for cooperation, and fortunately some substantial efforts in that direction are being made. But the de-escalation of tensions on the Korean Peninsula and the ultimate resolution to the issue depend on continued cooperation between China and the US. Or else, it will become even more difficult to resolve the issue.
China plays an important but limited role in the issue, and what the US expects it to do is simply not possible, as the two sides employ different approaches to resolve the issue. Besides, other issues such as the Tai-wan question may jeopardize Sino-US relations.
