Go do some research on China - it's economy is in the toilet and its leadership has destroyed much of it's success, foreign capital and companies have fled to India, Vietnam, Mexico, Indonesia.
Your lament of "Oh no China is the best in the world and only getting better!!!" is long long out of date.
With 2 billion people you’re absolute power. Internal market with middle class size of whole United States. No need for wallstreet and American style financial engineering. Producer of 80% goods for Europe. I mean buying something mainstream not made in China is barely possible. Technically there are some challenges like plane engines or lithography. But they’ll nail it. Trust me.
