We have to understand that China has never been able to enjoy such economic power at this level throughout their history, so they have been waiting for this position for such a long time. Their current position may potentially reshape future history of human civilization. When you have the entire country concentrating all their effort on one and only one objective, the rest will have to take a backseat. For example, China didn't have to spend trillion of dollars going to war which was also another reason why they were able to laser focus on just one single goal.
This definitely doesn't mean it would make China the most balanced country overall as everything in life is always a trade off. One may gain in one area but would always lose in another. I'm not saying people should be afraid of China, I'm only saying they should not lock themselves up in the old world, and instead be ready and willing to learn from others because obviously China must have been doing many things right to get here.
