they exercised sovereignty over the two archipelagos continuously and peacefully until they were invaded by Chinese armed forces. In Phủ biên tạp lục (撫邊雜錄, Miscellaneous Records of Pacification in the Border Area) by the scholar Lê Quý Đôn, Hoàng Sa (Paracel Islands), and Trường Sa (Spratly Islands) were defined as belonging to Quảng Ngãi District. In Đại Nam nhất thống toàn đồ (大南ー統全圖), an atlas of Vietnam completed in 1838, Trường Sa was shown as Vietnamese territory. Vietnam had conducted many geographical and resource surveys of the islands. The results of these surveys have been recorded in Vietnamese literature and history published since the 17th century. After the treaty signed with the Nguyễn dynasty, France represented Vietnam in international affairs and exercised sovereignty over the islands. The Cairo Declaration, drafted by the Allies and China towards the end of World War II, listed the territories that the Allies intended to strip from Japan and return to China. Despite China being among the authors of the declaration, this list did not include the Spratlys. Vietnam's response to China's claim that the Cairo Declaration somehow recognised the latter's sovereignty over the Spratlys is that it has no basis in fact. At the San Francisco Conference on the peace treaty with Japan, the Soviet Union proposed that the Paracels and Spratlys be recognised as belonging to China. This proposal was rejected by an overwhelming majority of the delegates. On 7 July 1951, Tran Van Huu, head of the Bảo Đại Government's (State of Vietnam) delegation to the conference declared that the Paracels and Spratlys were part of Vietnamese territory. This declaration met with no challenge from the 51 representatives at the conference. The text of the Treaty of San Francisco did not list the Spratlys, or any other island territories, to be returned to China. The Geneva Accords, which China was a signatory, settled the First Indochina War end. French Indochina was split into three countries: Laos, Cambodia and Vietnam. Vietnam was to be temporarily divided along the 17th Parallel. Chapter I, Article 4 states: On 26 October 1955, the Republic of Vietnam "South Vietnam" replaced the State of Vietnam (part of the French Union) and inherit of its rights. The Vietnamese government's Vietnam United Youth League, which runs the newspaper Thanh Niên News, claims that although, nothing was said explicitly about offshore archipelagos, which was of small interest by that times, it
