Also: language barriers and travel. Barley any non-Chinese sleek Chinese, sure it’s a difficult language to learn, but Chinese kids all study English from very early in their education. In China you can easily find foreign media with Chinese subtitles. How much Chinese media (including social media) do westerners consume?
If a Chinese person wants, they know how to, and can see western media. Many foreign movies are popular in China. Inversely, westerners have no idea about Chinese media, let alone Chinese culture, society, history, politics, etc.
A westerner would struggle to name a Chinese politician besides Xi; yet there are many who are influential. You can’t understand any countries politics by only knowing of their leader. Chinese history is many thousands of years old, yet Chinese kids also study western history and art, among other things.
I visited one of the most famous western (historical) art museums with a Chinese person, from the mainland, and they recognized as many prices of art as a person from that country would. This was in Europe (most Americans study art much less in their education).
Chinese people learn western languages, see western media, can travel to the west, and can study in their universities. Westerners largely do none of this when it comes to China. Even so, Chinese is a wonderful language, and China has incredible media, attractions, universities, etc.
In essentially all respects, westerners think they have a more accurate view of China because of their “democracy” and “free press”. Yet they are in reality so ignorant about China, that they are blind to the reality: westerners live in a box with one way mirrors looking back at them, they see their own atrocities in the reflection and project their crimes into others, yet those others can see the west clearly.
Even more amusing when you consider that DPRK has nukes, whereas Ukraine has only survived as a NATO proxy.
