China's new tack of being aggressively active in her neighbourhood has indeed left the US uncomfortable since it would be mean interactivity of the US in the Asia Pacific realm. It would also mean avoidable expenditure, be it to maintain a military deterrent in the region or wooing prospective 'allies' through aids and concessions that may not be in the US' financial interest. US is hardly in a position to squander its monies. Therefore, US would be most comfortable if China could be coaxed into its earlier avatar of 'peaceful rise'. But, a Tiger that has tasted human blood, will it stop being a maneater? Should China return to the policies of the era of her 'Peaceful Rise'? How will that be beneficial to her, when in actuality, she is on the threshold of becoming a cogent power that can challenge the US supremacy? And why should she?
