Tientsin Accord

The Tientsin Accord or Li–Fournier Convention, concluded on 11 May 1884, was intended to settle an undeclared war between France and China over the sovereignty of Tonkin (northern Vietnam). The convention, negotiated by Li Hung-chang for China and capitaine de vaisseau François-Ernest Fournier for France, provided for a Chinese troop withdrawal from Tonkin in return for a comprehensive treaty that would settle details of trade and commerce between France and China and provide for the demarcation of its disputed border with Vietnam.

Chinese opposition to French efforts to clamp a protectorate on Tonkin led to the outbreak of an undeclared war between France and China towards the end of 1883. Chinese troops fought alongside Liu Yung-fu's Black Flag Army during the Sơn Tây Campaign (December 1883). Although Admiral Courbet's capture of Son Tay paved the way for the eventual French conquest of Tonkin, the French now had to deal with open opposition from China as well as the Black Flag Army. Having exhausted diplomatic efforts to persuade the Chinese to withdraw their armies from Tonkin, the French government sanctioned an attack by General Charles Millot on the fortress of Bac Ninh, occupied since the autumn of 1882 by China's Guangxi Army. In March 1884, in the Bắc Ninh Campaign, Millot routed the Guangxi Army and captured Bắc Ninh.

The Chinese defeat at Bac Ninh, coming close on the heels of the fall of Sơn Tây, strengthened the hand of the moderate element in the Chinese government and temporarily discredited the extremist 'Purist' party led by Zhang Zhidong, which was agitating for a full-scale war against France. Further French successes in the spring of 1884, including the Capture of Hưng Hóa and Thái Nguyên, convinced the Empress Dowager Cixi that China should come to terms, and an accord was reached between France and China in May. The negotiations took place in Tianjin (Tientsin). Li Hung-chang, the leader of the Chinese moderates, represented China; and Captain François-Ernest Fournier, commander of the French cruiser Volta, represented France. The Tientsin Accord, concluded on 11 May 1884, provided for a Chinese troop withdrawal from Tonkin in return for a comprehensive treaty that would settle details of trade and commerce between France and China and provide for the demarcation of its disputed border with Vietnam.
