The environmental structure of China's diplomacy has changed since Xi Jinping came to power. What role China will play in global affairs, what policies it will pursue and what impact it will have on the world have become the focus of academic circles across the world.

This paper attempts to sort out the current situation of Korean academic research on China's diplomacy and find some clues of China's diplomacy, inorder to help Korean and Chinese academic researcher by providing advice within the capacity. In Korean academia, most of the research papers on China's foreign policy trends during the Period of Xi Jinping are limited by researchers' professional fields, and the research focusing on the overall research trends of diplomatic policy are not strong enough. This thesis uses the Net-miner4 program to clarify and analyze the recent research. Due to the limited time and space, the paper is in the process of finishing and writing. Hoping it could provide enlightenment to the related fields.
