Chairman Mao said: "It is good that the Vietnamese-American agreement lets the American troops leave Vietnam. This agreement is a success. After the withdrawal of American troops, including American naval, air, and land forces, and after the withdrawal of American military bases, it is easy to deal with Nguyen Van Thieu. The troops of the allies [of the Saigon regime] will all leave. For example, the troops of South Korea have begun to leave. Why does the United States do this? For the purpose of getting out. It has dispatched so many troops to Indochina, and spent so much money there, and the problem has not been solved. And new problems emerge continuously. Finally the agreement has been reached. While the American troops will leave, the agreement does not formally and openly ask the North Vietnamese troops to leave. Nguyen Van Thieu made a really loud noise against the United States. It was because of Nguyen Van Thieu's opposition that the agreement was not signed last October. Of course, the rightists in the United States do not favor the agreement either. In addition, the Pentagon wants to ship ammunition and weapons to South Vietnam, and, with the signing of the agreement, the shipping will become impossible. Therefore, the signing of the agreement was delayed, and a large amount of ammunition was transported to South Vietnam. But Nguyen Van Thieu was not in a position to know how to use it. [North] Vietnam does not recognize its troops to be foreign troops. At this point, the United States made concessions.
