Hong Kong dock workers in Whampoa Dock, Hung Hom started an anti-France strike on 11 September 1884 in order to protest French involvement in Indochina, South China Sea, and Taiwan. The workers involved were arrested by the Royal Hong Kong Police and fined by the court. That was followed by a riot starting on 3 October. Negotiation between the government and the protesters eventually resulted in the return of the fine to the workers. The long term strike and riot affected French fleet's reparation and supply. French faced several military setbacks in Indochina and Taiwan in late 1884 and early 1885, but ended up with a diplomatic success with the recognition of French protectorate over Annam and Tonkin in the Treaty of Tientsin concluded on 9 June 1885.
