Why is China so afraid of the western world? [closed]

Regardless of whether they admit it in public or not, China (or CCP) is afraid of the western world (esp. US or EU), even though now they rely on each other so heavily economically.

Through domestic education or propaganda, China is consistently educating its people or children that they should be careful of the western threat.

An example today is the Russia-Ukraine war. This is clearly an invasion from a western standpoint, but on China's domestic social media platform, the government seemingly stands together with Russia and blames the western world, telling its people that if Russia is taken down by the west, China will be the next one.

Why do they think this? Is it true that China cannot get along well with the West? Then how come Singapore can be good friends with the West?
