Following the Chinese Civil War, the Republic of China retained control of several islands close to the mainland. The People's Republic of China sought to assert sovereignty over these territories and to pressure the ROC and its U.S. backers, initiating heavy bombardment of Kinmen island in September 1954 as a direct military challenge to ROC-held offshore positions.
The PRC bombarded Kinmen, then extended shelling to Matsu and Tachen islands. The United States and ROC signed the Sino-American Mutual Defense Treaty in December 1954. The PRC seized the Yijiangshan Islands in January 1955, prompting the U.S. Congress to pass the Formosa Resolution authorizing President Eisenhower to defend ROC possessions. The U.S. Navy assisted ROC forces in evacuating the Tachen Islands.
The crisis de-escalated after Premier Zhou Enlai signaled willingness to negotiate at the Bandung Conference in April 1955, with shelling ending in May 1955. Ambassadorial-level talks between China and the United States began in Geneva in August 1955. However, underlying disputes over the offshore islands and Taiwan's status remained unresolved, directly contributing to the Second Taiwan Strait Crisis three years later.
