This is revenge for the "100 years of shame". China is at war with the West.
The US helped China re the Empire of Japan and WW2.
The US helped China re the Soviets.
The US was responsible for China gaining access to the WTO, which rapidly transformed their economy.
The US helped China develop by pouring trillions of dollars in capital into their country and trading with them in a mutually beneficial manner.
No other dominant world power in the last ~500 years has ever treated China with that kind of respect. As recently as 1992, the US had an economy 15 times the size of China, and it didn't seek to conquer them or humiliate them.
