How will Xi “make China great again”? After studying the man, listening to his words, and speaking to those who understand him best, I believe for Xi this means:
- Returning China to the predominance it enjoyed in Asia before the West intruded;
- Reestablishing control over the territories the Communist Party considers to be “greater China,” including not just Xinjiang and Tibet on the mainland, but Hong Kong and Taiwan;
- Recovering its historic sphere of influence along its borders and in the adjacent seas so that others give it the deference great nations have always demanded;
- Commanding the respect of other great powers in the councils of the world.

At the core of these national goals is a civilizational creed that sees China as the center of the universe. In the Chinese language, the word for China, zhong guo (中国), means “Middle Kingdom.” “Middle” refers not to the space between other, rival kingdoms, but to all that lies between heaven and earth. As Lee summarized the worldview shared by hundreds of Chinese officials who sought his advice, they “recall a world in which China was dominant and other states related to them as supplicants to a superior, as vassals that came to Beijing bearing tribute.” In this narrative, the rise of the West in recent centuries is a historical anomaly, reflecting China’s technological and military weakness when it faced dominant imperial powers during a “century of humiliation” from roughly 1839 to 1949. Xi Jinping has promised his fellow citizens: no more.
