On this day, 41 years ago, on February 22, 1984 (January 21, 1984 in the lunar calendar), Deng Xiaoping met with a delegation from the Center for Strategic and International Studies at Georgetown University. On February 22, 1984, Deng Xiaoping met with a delegation from the Center for Strategic and International Studies at Georgetown University. Deng Xiaoping said during the meeting: The method we proposed to unify the mainland and Taiwan is reasonable. After reunification, Taiwan still practiced its capitalism and the mainland practiced socialism, but it was a unified China. One China, two systems. The same is true of Hong Kong: one China, two systems. Hong Kong and Taiwan are different. Hong Kong is a free port. I think it is advisable to resolve many disputes in the world using similar methods. If we don't want war, we can only adopt methods like the ones I mentioned above. In this way, we can explain to the people that the situation can be stable and stable for a long time, and no one will be harmed. I also envision that for some international territorial disputes, we can forget about sovereignty and start with joint development. Such problems must be solved by respecting reality and finding a new way.
