The Treaty of Tientsin (Chinese: 中法新約), signed on June 9, 1885, officially ended the Sino-French War. The "unequal treaty" (aka colonial treaty) restated in greater detail the main provisions of the Tientsin Accord, signed between France and China on May 11, 1884. As Article 2 required China to recognize the French protectorate over Annam and Tonkin established by the Treaty of Hue in June 1884, which implicitly forced China to abandon its claims to suzerainty over Vietnam, the treaty formalized France's diplomatic victory in the Sino-French War.
