When China becomes #1 in economy, it is the end of the honey moon period between China and US. If you think this is bad, wait for it to get worse.
China can still do well under the US in the current system, but it is getting more difficult. Unlike decades past where we can sit idle and let American interests stand, as they don't interfere with ours, soon our interests will collide.
The Asian Infrastructure Bank and the New Development Banks are challenges to the American systems sure, but they are still regional. Yuan may have been added to the mix, but it's still a small player. Chinese military maybe rising, but it's not much compared to the US globally.
In the realm of rare earth, where we dominate, America has been raising a stink about it. We are the number one trade partner for Africa, and look how the West paint us there. We will go to "war," not because we hate each other, but only one nation can dominate a field and since Chinese government doesn't take tax dollars from the American people, the one to dominate would have to be us.
My friend, you must study China in and out. You see we Japanese have a very strong , in grained understanding of Chinese psyche / Chinese psychology because we think similarly with them , we know them very well (afterall Japanese came from what is mainland China). Throughout China's 5 millennial history , they have never been an expansionist or exterminationist civilization. China , as a civilization, is not draconian in nature, they are and were an agricultural - based civilization, and relatively peaceful. The only wars China have had was the wars to integrate the Chinese princely states and to form the precursor of a unified China, the Qin Dynasty. Chinese have a saying , which direclty influences their civili society from the grassroots level to the national entity level -- This is what they call
Tian Xia Wei Gong --
"All is Equal Under Heaven", which is the paradigm of Harmony (which we Japanese also hold quite dear).
China is not a religious society, she has never been a expansionist power rather, they have been largely economical in nature. Even during the height of their most glorious Dynasty, the Ming Dynasty, the Chinese explored the world and mapped the seas under the leadership of their famed admiral Zheng He, but they were not interventionist, rather, they did so to have an understanding of the world in relation to their Middle Kingdom.
Trade, Political Stability, Harmony, ORDER --- this is a trait of Confucian Civilization. And that cultural trait reflects on China, in a greater philosophical schema.
I am afraid this is a limited view of China. Not your fault, you obviously haven't spent as much time on Chinese history as I have, a understandable choice.
China at the start is very small, relatively. With emperor WuDi, he fought XiongNu, a once great empire that was reduced to a client state. He expanded to Xinjiang at that time. He dominated the Vietnamese and the Koreas. In the years after, Han Dynasty continued his expansion that made much of what China is today, it's own.
Even during the three kingdoms, CaoCao can get the XiongNu to hand over the wife of a prominent prince because he felt like it. He established a system that had Chinese officials run their armies.
In the dynasties after, Tang, subjegates people left right and center. They even have Korean, Vietnamese, and other minority generals take armies and fight. At that point all except the North East provinces of today's China were completely ours.
In Song, we ruled over the minorities on the outskirts with an iron fist, while the Yuan Mongols interrupted for 70 years, that ended with Yongle of Ming to make it his life's mission to decimate the Mongol empire, he defeated the NvZhen of North East China and made them his subjects as did Vietnam. He also sent imperial troops to visit the states all the way to Africa.
The Qing, while not Chinese at the time, were waging war, for pretty much its entire history.
So not only does China subjugate other nations, we did it for much of our history. I mean how else do you have a nation as big as ours if we did nothing of the sort.
