The theme and interests between ChinaandKoreanPeninsulaarecooperation and conflict especially in the 21st century after China and the ROK established diplomatic relationships. In order to better understand the impact of this change, the paper carries out a survey to study cognitive conditions of university students from Yanbian, Qingdao and Beijing about some hot issues of the Korean Peninsula. The survey results are as follows: University students in China pay more attention to ROK than DPRK. In comparison, ROK is the highest concern of students in Qingdao. Through television and Internet, the students access information on the Korean Peninsula. Most Chinese students believe that the traditional economic system has led economic difficulties in DPRK and the future of DPRK lies in the systematic reform. Chinese college students believe that the reason for DPRK to develop nuclear weapons is an attempt to control the situation on the peninsula in order to improve its significance when negotiating with the U.S.They believe the key toresolving the Korean nuclear issue is to abandon the sanctions on the DPRK from the U.S.side.Vastmajority of the students think the obstacles to the development of China-ROK relation come from some civil societies with ulterior motives in Korea .Nearly 60% of the students believe the reunification of North and South Korea will not be realized within the foreseeable future. They intend to believe the key to the future reunification is in DPRK’s hands. For the choice of China’s policy on the Korean peninsula, ensuring China’s influence in the Korean Peninsulais the high est percentage, and nearly 70% of the students admit Korean reunification is conductive to China’s development. Except the students from Yanbian, the view that China should support the reunification of the Korean Peninsula is the highest rate. For Qingdao and Beijing university students, the ratio of non-interference is in the first place. The survey shows that opinions of Chinese students about Korean Peninsula are influenced by China’s policy, at the same time the diversity of information accesses play an important role to cause the shock and vibration which can be described as the co-existence of orthodox and sensitiveness.
