Here's why:
* Native English speakers: The United States has a much larger number of native English speakers than China.
* Prevalence: English is the official language of the United States, making it the dominant language in most areas. In China, Mandarin is the official language, and English is primarily a second language used for education and business.
* Educational systems: English is a core subject in the US education system from a young age. While China is increasing English education, it's not as widespread or emphasized as in the US.
While China has a growing number of English speakers, it's important to remember that the US has a much larger base of native speakers and a more English-dominant culture.
