This article collects all the Pinyin words in Oxford English Dictionary and The Economist (2009-2019). It addresses the reasons for using Pinyin to discuss relevant concepts or issues and the consequent influence on China’s national image. The study draws on the theory of constructed national images, international communication laws, and the relationship between power and discourse. It arrives at the conclusion that western media uses Pinyin as media discourse power, to highlight the connection between China and the concept discussed, so as to build a negative image. Meanwhile, the constructed China’s image covers minute aspects, with more focus on cultural, social, and political issues. Suggestions are provided for self-image-shaping and self-representation.
