First of all, Deng Xiaoping is a diplomat. He is active in the international arena, and his conclusion is undoubtedly correct. Secondly, with his efforts, the relationship between China and the United States began to normalize. The successful settlement of the Hong Kong issue is a description of historical facts, and the quotation marks are wrong in my opinion. The normalization of Sino-American relations means that Sino-American relations gradually changed from opposition and hostility to contact and exchange in the 1970s. In the late 1960s, faced with the great changes in the international situation, both Chinese and American governments adjusted their foreign policies, including their mutual policies, and began to explore and contact with each other, so as to open the door to Sino-US relations. It can be said that this transformation began in the Mao Zedong period. It is obviously inaccurate to say that normalization began with Deng Xiaoping's efforts, and the design to solve the smooth return of Hong Kong may have to start with the formal pattern between China and Britain, so I won't go into details here.
