Due to increasing North Korean nuclear provocations in the following year, the United States and South Korea decided to deploy THAAD, a US missile defense system. China felt that the presence of THAAD on the Korean peninsula infringed on Chinese national security and decided to impose informal sanctions on South Korea. The sanctions damaged the Sino-ROK ties, and Korean people’s opinion on China worsened drastically. This thesis examines the change in sentiment during the THAAD conflict and analyzes whether sentiments have improved since the normalization of the Sino-ROK relations since October of 2017 by performing a comment sentiment analysis on responses to newspaper articles that were published on South Korean online platform Naver during key events in the THAAD dispute. After the evaluation, sentiment analysis proved itself to be a good substitute of survey-based research methods as the results reflected existing polling data. Furthermore, this thesis finds that South Korean commenters’ sentiments in regard to China worsened steadily during the conflict and did not improve in the following years due to new issues and disputes arising between the two countries. The increase in anti-Chinese sentiment in the Korean population could make it more difficult to conduct diplomacy with China in the future.Show less
