After the 1884–1885 Sino-French War, in an international context, France officially gained control of Annam and Tonkin as protectorates and fully established French colonial rule in Vietnam by signing a number of treaties with Chinese and Vietnamese governments including Tientsin Accord, Treaty of Huế (1884) and Treaty of Tientsin (1885). Article 2 of the Treaty of Tientsin (1885) forced China to stop any claims to suzerainty all over Vietnam. Therefore, the French also took over the control of the Paracel Islands which were under the Nguyễn dynasty's administration, still nominally ruled Annam at the time.
