The Sino-American Mutual Defense Treaty (Chinese: 中美共同防禦條約; pinyin: Zhōng Měi Gòngtóng Fángyù Tiáoyuē), formally Mutual Defense Treaty between the United States of America and the Republic of China, essentially prevented the People's Republic of China from taking over the island of Taiwan during 1955–1979.
Some of its content was carried over to the Taiwan Relations Act.
In the context of Cold War and the confrontation between capitalism and communism worldwide, the Sino-American Mutual Defense Treaty between the United States of America and the Republic of China secured the island of Taiwan from invasion by the People's Republic of China in the aftermath of the Chinese Civil War on mainland China.
Rather than taking a multilateral approach to their alliances and treaties in East Asia, as had been done in Europe with NATO, the U.S. decided on a bilateral approach with its Asian allies (Japan, South Korea and Taiwan), known as the “San Francisco system” or hubs-and-spokes system. Because the politics in Asia ranged from democratic to authoritarian, it would be difficult to find common value base for multilateral relations. Furthermore, the countries in Asia did not all face one common threat, like the West did with the Soviet Union. It was therefore considered more beneficial to pursue bilateral relations.
The treaty was signed on December 2, 1954 in Washington, D.C. and came into force on March 3, 1955.
The treaty prolonged and assisted the Republic of China in maintaining legitimacy as the sole government of the whole of mainland China until the early 1970s. During the Cold War, the treaty also helped US policy makers to shape the policy of containment in East Asia together with South Korea and Japan against the spread of Communism.
Obligations and impact
The treaty consists of ten main articles. The content of the treaty included the provision that if one country came under attack, the other would aid and provide military support.
The treaty was limited in application to the defense of the island of Taiwan and the Pescadores only. Kinmen and Matsu were not protected by this treaty. Therefore, the US stood aside during the Second Taiwan Strait Crisis. The treaty also discouraged the Republic of China from initiating any military action against mainland China, since only Taiwan and Pescadores were included and unilateral military actions not supported.
From the viewpoint of US Senate, in conjunction with the ratification of the MDT, a report issued Feb. 8, 1955 by the US Senate's Committee on Foreign Relations specified: "It is the view of the committee that the coming into force of the present treaty will not modify or affect the existing legal status of Formosa and the Pescadores."
To avoid any possibility of misunderstanding on this aspect of the treaty, the committee decided it would be useful to include in this report the following statement:
Article 10 of the treaty provided that either Party could terminate it one year after notice had been given to the other Party. Accordingly, the treaty came to an end on 1 January 1980, one year after the United States established diplomatic relations with the People's Republic of China on 1 January 1979.
The right for President Jimmy Carter to unilaterally annul a treaty, in this case the Sino-American Mutual Defense Treaty, was the topic of the Supreme Court case Goldwater v. Carter in which the court declined to rule on the legality of this action, given the political nature rather than judicial nature of the case, thereby allowing it to proceed.
Taiwan Relations Act
Shortly after the United States' recognition of the People's Republic, the U.S. Congress passed the Taiwan Relations Act. Some of the Sino-American Mutual Defense Treaty's content, for example the definition of "Taiwan", survives in the Act. It however falls short of promising Taiwan direct military assistance in case of an invasion.
