In this project, the topic of factors that affect prejudice between China, Japan, and Korea will be discussed. The primarily negative relationship between these East Asian countries has been impacting the lives of citizens throughout history, especially now, with the help of social media. Harmful stereotypes such as “cold and unreliable Japanese”, “untrustworthy Chinese”, and “culture stealing Koreans” cause discourse such as the Chinese people rejecting aid that the Japanese government sent during COVID-19, the school textbooks that paint each other in a negative light by using “fake history”, and fights that often break out between Chinese, Japanese, and Korean people on social media. By researching articles written previously on this subject, I found that some factors that might affect the prejudice between these three East Asia countries are views of historical animosity, such as atrocities committed by Japan in World War II and Imperial Japan’s invasions, political needs within the countries, and current military advances including the fight of claim over the Diaoyu islands in the East China Sea. Ultimately, these stereotypes and prejudice do not need to exist as they are not backed by any scientific reasoning, being mostly motivated by amplified emotions caused by propaganda. By conducting this research, I hope to shed some light on the prejudices that affect the relationship between Chinese, Japanese, and Korean people and help them understand each other better, which is the first step towards dispelling unreasonable stereotypes.

Project review

“I gained so much new knowledge about how to properly research, such as what websites to use, how in-text citations work, and how a research essay is properly structured. This is the knowledge I never knew I needed. I also exceeded my own expectations of this project by including actual data using graphs I made in Excel. Polygence provided me with 10/10 support. The writing feedback was detailed and immediate, while my mentor's feedback opened my eyes every time. She pointed out a lot of my bad writing habits, such as the tendency to overcomplicate sentences, and using a lot of unnecessary quotes. I learned so much about writing from her.”
