Chinese exceptionalism is when China is seen as different from other countries. It means that people think China has rules and beliefs that are different from countries in the rest of the world. For example, they have a different political system than most other countries, and they have a very long history and culture that is different from other countries. China is also one of the most powerful countries in the world, with the world's largest population and the world's second-largest economy. This combination can make people think that China is unique in the world and needs to be treated differently.
