The characters for China 中国 are often translated in English as Middle Kingdom.
What is lost is the meaning behind those characters:
that China is the centre of the world - the nation to which all other nations should naturally and rightfully kowtow and pay tribute.
That this was not the case since the Opium Wars, the Unequal Treaties imposed by the Western powers, and the Japanese occupation of Manchuria
resulted a cognitive dissonance in the national psyche: a well balanced personality with a chip on both shoulders.
Most in the West have forgotten these events, but they are still perceived by many in China as righteous grievances - a humiliating loss of face yet to be regained.
Japan's response to gunboat diplomacy was rapid modernization - the Meiji Restoration. In China such efforts were thwarted.
Including a long excursion into one of the greatest idiocies in history - Maoism.
[Side note. Sun Yat Sen, the founder of modern China, spent about 10 years in Japan supported and aided by those opposed to what was perceived as Western imperialism.]
Of course, the progress in China since the reforms of Deng Xiao Ping have been remarkable. Yet the CCP is still insecure about it's legitimacy and ultimately it's survival.
The problem of endemic corruption has not been properly addressed.
The younger generations, not having experienced war or the privations of Maoism, and educated in history with Chinese characteristics are even more nationalistic.
A point that Torchwood has made, I think, in various posts.
One only has to read the Chinese posts on, say, The Edge [atimes.com]. They make the shrillest Spenglermanian sycophant look sane and reasonable.
So for these reasons, while I don't always agree with the implementation of
Pax Americana, I don't think that the rest of E and SE Asia, would welcome a
Pax Sinica.
Better the devil you know . . .

And as noddy pointed out, better two powers competing than one dominant.
Never criticize anyone until you've walked several kilometres in their shoes.
Because
1. You're now several kilometres away; and
2. You've got their shoes.
