In this interview given by Wen Jiabao to ROK news agencies, including Yonghap News, Chosun Ilbo, Dong-A Ilbo and KBS, the Chinese Premier spoke his views of how to resovle the issue of unification on the Peninsula, of the dispute between China and the ROK over the history of Koguryo, of China-ROK trade relations, and others.
From Wen's answers, you really can see, China regards the trade as the most important. Because of that, the Chinese government suppresses many sensitive issues in the media, such as the "Koguryo" dispute. The public generally won't read academic articles for historical truth, and they are used to consuming "fast food." So many Korean Chinese got one-sided views by reading the Korean newspapers regarding the history of Koguryo. As a result, the Chinese government may have kept the China-ROK trade going, but lost the hearts of some Chinese Koreans.
