Chang is a high-ranking admiral in the Chinese military who planned to overthrow the current Chinese government. He orders the assassination of Jin Jié, the future leader and voice for peace and progress in China. Despite failing, Chang was able to implicate the United States for Jié's death and cancels elections whilst declaring martial law. This, in turn, causes both US and Russian navies to station themselves off the coast of China as civil unrest increases and protests begin in Shanghai.
